South Korea KT to pay USD$33.97 million for network outage
by Sean Donelan 01 Nov '21

01 Nov '21

https://www.koreatimes.co.kr/www/tech/2021/11/133_318025.html KT to pay W40 bil. in compensation for network outage KT will pay out up to 40 billion won ($33.97 million) in compensation to customers of its wired and wireless services, which underwent nationwide disruptions Oct. 25, the company said. [...] KT said it will pay compensation for 10 times the disruption time of 89 minutes... [...] NTT Docomo, AT&T, Verizon and T-Mobile caused disruptions in services for subscribers (customers) in recent years, but none offered compensation. "We are offering the greatest level of compensation compared to both local and foreign companies in the same industry," a KT official said. [...] The Ministry of Science and ICT said the mistake of an employee of a KT subcontractor caused the nationwide disruption.

Re: Need for historical prefix blacklist (`rogue' prefixes)
by Jakob Heitz (jheitz) 01 Nov '21

01 Nov '21

It may be possible to create a fake certificate for a fake ROA. However, to do that requires a lot of steps to go right. First, the RSA private key needs to be derived from the public key. The quantum computer physics exists to do it. However, the known technology is massively behind and may never materialize. OTOH, it is a wide open field and someone may find a way to create enough qubits and entangle them all and keep them stable long enough to perform the calculation tomorrow. People have been trying for several years, so this is extremely unlikely. Second, relying parties need to be convinced/tricked into downloading the fake certificates. Since each certificate contains the publication points of its child certificates, the certs are chained together. The route to a publication point needs to be hacked to cause relying parties to access the fake publication point. A point was made that encrypted data can be captured and stored and then be decrypted later once the technology becomes available. This possibility is not useful for creating fake ROA certs. Therefore quantum resistant certificates will not be needed in advance of the development of quantum certificate crackers.

Re: PCH Peering Survey 2021
by Adam Thompson 01 Nov '21

01 Nov '21

Question: if I have a written contract with a peer that covers the link and IP service in general, but that contract does not specifically discuss BGP or peering, is that a Yes or No? Also, how should I indicate "unknown" , particularly for the Written Contract field? -Adam Adam Thompson Consultant, Infrastructure Services [1593169877849] 100 - 135 Innovation Drive Winnipeg, MB, R3T 6A8 (204) 977-6824 or 1-800-430-6404 (MB only) athompson(a)merlin.mb.ca<mailto:athompson@merlin.mb.ca> www.merlin.mb.ca<http://www.merlin.mb.ca/> ________________________________ From: NANOG on behalf of Bill Woodcock Sent: Friday, October 29, 2021 06:47 To: NANOG Subject: PCH Peering Survey 2021 Background: Five and ten years ago PCH conducted comprehensive global surveys characterizing Internet peering agreements. They are the only ones of their kind, and are relied upon by legislators and regulators throughout the world to understand the Internet interconnection landscape. Our write-ups of the prior surveys can be found here: https://www.pch.net/resources/Papers/peering-survey/PCH-Peering-Survey-2011… https://www.pch.net/resources/Papers/peering-survey/PCH-Peering-Survey-2016… …and video of the NANOG presentation of the 2016 results is here: https://www.youtube.com/watch?v=lPuoBmxyXMc At the time of the 2011 survey, we committed to repeating the survey every five years, to provide time-series data about the direction peering trends take. We’re now conducting the third iteration of the survey. Among other things, the surveys have helped establish a better understanding of trends in: • The increasingly uniform global norms of interconnection • National preferences within the network operator community for country of governing law • The long tail of small networks which don’t yet support IPv6 routing • The significance of multilateral peering agreements in the density of the interconnection mesh These findings, particularly the first, have been invaluable in giving regulators in the vast majority of the world’s countries a data-driven basis for refraining from prescriptively regulating Internet interconnection. They have demonstrated in objective terms that the Internet self-regulates in a way that’s more globally uniform and closely harmonized than any coordination of national regulatory bodies could accomplish. Participation: The survey is global in scope, and our goal is to reflect the diversity of peering agreements in the world. Your participation ensures that your norms and ways of doing business are represented accurately and proportionately in the dataset. If you don’t participate, the way you do business will be less well-represented in the data, and will seem less normal to regulators and policy-makers. We’re interested in large ISPs and small ISPs, ISPs in Afghanistan and in Zimbabwe, bilateral agreements and multilateral, private and public. Our intent is to be as comprehensive as possible. In 2011, the responses we received represented 4,331 networks in 96 countries, or 86% of the world’s ISPs at that time. In 2016, responses represented 10,794 networks in 148 countries, or 60% of the world’s ISPs in 2016. Our aim is to be equally inclusive this year. Since our principal method of soliciting participation is via NOG mailing lists, I’m afraid many of you will see this message several times, on different lists, for which we apologize. Privacy: In 2011 and 2016, we promised to collect the smallest set of data necessary to answer the questions, to perform the analysis immediately, and not to retain the data after the analysis was accomplished. In that way, we ensured that the privacy of respondents was fully protected. We did as we said, no data was leaked, and the whole community benefited from the trust that was extended to us. We ask for your trust again now as we make the same commitment to protect the privacy of all respondents, using the same process as was successfully employed the last two times. We are asking for no more data than is absolutely necessary. We will perform the analysis immediately upon receiving all of the data. We will delete the data once the analysis has been performed. The Survey: We would like to know your Autonomous System Number, and the following five pieces of information relative to each other AS you peer with: • Your peer’s ASN (peers only, not upstream transit providers or downstream customers) • Whether a written and signed peering agreement exists (the alternative being a less formal arrangement, such as a "handshake agreement") • Whether the terms are roughly symmetric (the alternative being that they describe an agreement with different terms for each of the two parties, such as one compensating the other, or one receiving more or fewer than full customer routes) • Whether a jurisdiction of governing law is defined • Whether IPv6 routes are being exchanged (this year, we’ll still assume that IPv4 are) The easiest way for us to receive the information is as a tab-text or CSV file or an Excel spreadsheet, consisting of rows with the following columns: Your ASN: Integer Peer ASN: Integer Written agreement: Boolean [true,1,yes,y] or [false,0,no,n] Symmetric: Boolean [true,1,yes,y] or [false,0,no,n] Governing Law: ISO 3166 two-digit country-code, or empty IPv6 Routes: Boolean [true,1,yes,y] or [false,0,no,n] For instance: 42 <tab> 715 <tab> false <tab> true <tab> us <tab> true <cr> 42 <tab> 3856 <tab> true <tab> true <tab> us <tab> true <cr> We need the ASNs so we can avoid double-counting a single pair of peers when we hear from both of them, and so that when we hear about a relationship in responses from both peers we can see how closely the two responses match, an important check on the quality of the survey. As soon as we've collated the data, we will protect your privacy by discarding the raw data of the responses, and only final aggregate statistics will be published. We will never disclose any ASN or any information about any ASN. If you’re peering with an MLPA route-server, you’re welcome to include just the route-server’s ASN, if that’s easiest, rather than trying to include each of the peer ASNs on the other side of the route-server. Either way is fine. If all of your sessions have the same characteristics, you can just tell us what those characteristics are once, your own ASN once, and give us a simple list of your peer ASNs. If your number of peers is small enough to be pasted or typed into an email, rather than attached as a file, and that’s simpler, just go ahead and do that. If you have written peering agreements that are covered by non-disclosure agreements, or if your organizational policy precludes disclosing your peers, but you’d still like to participate in the survey, please let us know, and we’ll work with whatever information you’re able to give us and try to ensure that your practices are statistically represented in our results. If you're able to help us, please email me the data in whatever form you can. If you need a non-disclosure, we're happy to sign one. Finally, if there are questions you’d like us to try to answer when we analyze the data, please suggest them, and if there are any additional questions you’d like us to include in future iterations of the survey, please let us know so that we can consider including them in the 2026 survey. Please respond by replying to this email, by the middle of November, two weeks from now. Thank you for considering participating. We very much appreciate it, and we look forward to returning the results to the community. -Bill Woodcock Executive Director Packet Clearing House

Comcast? Layer2 / ELAN
by Joe Carroll 29 Oct '21

29 Oct '21

Greetings Fellow Nanog'ers Are there any Comcast engineers in the group that could help to sort out a 10GB layer2 ELAN issue in Florida? We are short of cancelling this circuit that has been in for a couple of days. We cannot pass above 1GB on this circuit... 10GB SFPs on both ends, 10GB price, 1GB service... the team refuses to investigate, dispatch, or otherwise act in any way that is customer oriented. Regards, -Joe

PCH Peering Survey 2021
by Bill Woodcock 29 Oct '21

29 Oct '21

Background: Five and ten years ago PCH conducted comprehensive global surveys characterizing Internet peering agreements. They are the only ones of their kind, and are relied upon by legislators and regulators throughout the world to understand the Internet interconnection landscape. Our write-ups of the prior surveys can be found here: https://www.pch.net/resources/Papers/peering-survey/PCH-Peering-Survey-2011… <https://www.pch.net/resources/Papers/peering-survey/PCH-Peering-Survey-2011…> https://www.pch.net/resources/Papers/peering-survey/PCH-Peering-Survey-2016… <https://www.pch.net/resources/Papers/peering-survey/PCH-Peering-Survey-2016…> …and video of the NANOG presentation of the 2016 results is here: https://www.youtube.com/watch?v=lPuoBmxyXMc <https://www.youtube.com/watch?v=lPuoBmxyXMc> At the time of the 2011 survey, we committed to repeating the survey every five years, to provide time-series data about the direction peering trends take. We’re now conducting the third iteration of the survey. Among other things, the surveys have helped establish a better understanding of trends in: • The increasingly uniform global norms of interconnection • National preferences within the network operator community for country of governing law • The long tail of small networks which don’t yet support IPv6 routing • The significance of multilateral peering agreements in the density of the interconnection mesh These findings, particularly the first, have been invaluable in giving regulators in the vast majority of the world’s countries a data-driven basis for refraining from prescriptively regulating Internet interconnection. They have demonstrated in objective terms that the Internet self-regulates in a way that’s more globally uniform and closely harmonized than any coordination of national regulatory bodies could accomplish. Participation: The survey is global in scope, and our goal is to reflect the diversity of peering agreements in the world. Your participation ensures that your norms and ways of doing business are represented accurately and proportionately in the dataset. If you don’t participate, the way you do business will be less well-represented in the data, and will seem less normal to regulators and policy-makers. We’re interested in large ISPs and small ISPs, ISPs in Afghanistan and in Zimbabwe, bilateral agreements and multilateral, private and public. Our intent is to be as comprehensive as possible. In 2011, the responses we received represented 4,331 networks in 96 countries, or 86% of the world’s ISPs at that time. In 2016, responses represented 10,794 networks in 148 countries, or 60% of the world’s ISPs in 2016. Our aim is to be equally inclusive this year. Since our principal method of soliciting participation is via NOG mailing lists, I’m afraid many of you will see this message several times, on different lists, for which we apologize. Privacy: In 2011 and 2016, we promised to collect the smallest set of data necessary to answer the questions, to perform the analysis immediately, and not to retain the data after the analysis was accomplished. In that way, we ensured that the privacy of respondents was fully protected. We did as we said, no data was leaked, and the whole community benefited from the trust that was extended to us. We ask for your trust again now as we make the same commitment to protect the privacy of all respondents, using the same process as was successfully employed the last two times. We are asking for no more data than is absolutely necessary. We will perform the analysis immediately upon receiving all of the data. We will delete the data once the analysis has been performed. The Survey: We would like to know your Autonomous System Number, and the following five pieces of information relative to each other AS you peer with: • Your peer’s ASN (peers only, not upstream transit providers or downstream customers) • Whether a written and signed peering agreement exists (the alternative being a less formal arrangement, such as a "handshake agreement") • Whether the terms are roughly symmetric (the alternative being that they describe an agreement with different terms for each of the two parties, such as one compensating the other, or one receiving more or fewer than full customer routes) • Whether a jurisdiction of governing law is defined • Whether IPv6 routes are being exchanged (this year, we’ll still assume that IPv4 are) The easiest way for us to receive the information is as a tab-text or CSV file or an Excel spreadsheet, consisting of rows with the following columns: Your ASN: Integer Peer ASN: Integer Written agreement: Boolean [true,1,yes,y] or [false,0,no,n] Symmetric: Boolean [true,1,yes,y] or [false,0,no,n] Governing Law: ISO 3166 two-digit country-code, or empty IPv6 Routes: Boolean [true,1,yes,y] or [false,0,no,n] For instance: 42 <tab> 715 <tab> false <tab> true <tab> us <tab> true <cr> 42 <tab> 3856 <tab> true <tab> true <tab> us <tab> true <cr> We need the ASNs so we can avoid double-counting a single pair of peers when we hear from both of them, and so that when we hear about a relationship in responses from both peers we can see how closely the two responses match, an important check on the quality of the survey. As soon as we've collated the data, we will protect your privacy by discarding the raw data of the responses, and only final aggregate statistics will be published. We will never disclose any ASN or any information about any ASN. If you’re peering with an MLPA route-server, you’re welcome to include just the route-server’s ASN, if that’s easiest, rather than trying to include each of the peer ASNs on the other side of the route-server. Either way is fine. If all of your sessions have the same characteristics, you can just tell us what those characteristics are once, your own ASN once, and give us a simple list of your peer ASNs. If your number of peers is small enough to be pasted or typed into an email, rather than attached as a file, and that’s simpler, just go ahead and do that. If you have written peering agreements that are covered by non-disclosure agreements, or if your organizational policy precludes disclosing your peers, but you’d still like to participate in the survey, please let us know, and we’ll work with whatever information you’re able to give us and try to ensure that your practices are statistically represented in our results. If you're able to help us, please email me the data in whatever form you can. If you need a non-disclosure, we're happy to sign one. Finally, if there are questions you’d like us to try to answer when we analyze the data, please suggest them, and if there are any additional questions you’d like us to include in future iterations of the survey, please let us know so that we can consider including them in the 2026 survey. Please respond by replying to this email, by the middle of November, two weeks from now. Thank you for considering participating. We very much appreciate it, and we look forward to returning the results to the community. -Bill Woodcock Executive Director Packet Clearing House

What are best practices for RPKI ROV in transit networks....
by ssw＠iu.edu 29 Oct '21

29 Oct '21

Greetings, We seek input on best practices for implementing RPKI ROV in a transit (partial transit) network. The Internet2 network provides partial transit for many of the K-12 and higher education institutions in the US. Our customer routes number just over 6,000. We work with our customers to assist with the adoption of MANRS, including creating RPKI ROAs for their resources. At some point in the future, we'd like to implement RPKI route origin validation (e.g., dropping invalids). Given that some routes may have mistaken ROAs that resolve to an invalid state, is there a standard/best practice for processing exceptions? Or, do transit providers that implement ROAs drop all routes that are invalid? Thanks, Steve

Re: S.Korea broadband firm sues Netflix after traffic surge

Not to be outdone, British Telecom joins the cephalopod games: “Every Tbps (terabit-per-second) of data consumed over and above current levels costs about £50m,” says Marc Allera, the chief executive of BT’s consumer division. “In the last year alone we’ve seen 4Tbps of extra usage and the cost to keep up with that growth is huge.” “When the rules were created 25 years ago I don’t think anyone would have envisioned four or five companies would be driving 80% of the traffic on the world’s internet. They aren’t making a contribution to the services they are being carried on; that doesn’t feel right.” “A lot of the principles of net neutrality are incredibly valuable, we are not trying to stop or marginalise players but there has to be more effective coordination of demand than there is today” https://www.theguardian.com/business/2021/oct/10/squid-games-success-reopen… For reference British Telecom has about 10 million broadband subscribers, so apparently those £200m capacity upgrades are stinging. All in all, this raises an interesting question. Is British Telecom running their networks so hot, that just keeping the lights on requires capacity upgrades or are they just looking for freebies? - Jared
