FCC: Staff Report on T-Mobile Outage on June 15 2020
by Sean Donelan 13 Nov '20

13 Nov '20

FCC Issues Staff Report On T-Mobile Outage https://www.fcc.gov/document/fcc-issues-staff-report-t-mobile-outage-0 The outage was initially caused by an equipment failure and then exacerbated by a network routing misconfiguration that occurred when T-Mobile introduced a new router into its network. In addition, the outage was magnified by a software flaw in T-Mobile’s network that had been latent for months and interfered with customers’ ability to initiate or receive voice calls during the outage. [...] 44. While fiber link failures are common, PSHSB finds that these steps, taken together, will reduce the likelihood that a fiber link failure could result in the recurrence of a similar event in TMobile’s network because traffic would be routed to an alternative path that could handle it. Moreover, if such an event recurred on T-Mobile’s network, it would not cause such a large service disruption because T-Mobile would have improved its networks’ ability to manage congestion in the case of a similar event and would have increased network capacity to maintain the network in a working state even with an increased volume of traffic.

Fwd: [apnic-talk] APRICOT 2021 PC call for volunteers
by Mark Tinka 12 Nov '20

12 Nov '20

FYI. Mark. -------- Forwarded Message -------- Subject: [apnic-talk] APRICOT 2021 PC call for volunteers Date: Thu, 12 Nov 2020 20:37:10 +1000 From: Philip Smith <pfsinoz(a)gmail.com> Reply-To: APRICOT PC Chairs <pc-chairs(a)apricot.net> Organization: PFS Internet Development Pty Ltd To: apnic-talk(a)lists.apnic.net CC: APRICOT PC Chairs <pc-chairs(a)apricot.net> Hi everyone, As you will no doubt be aware, due to the COVID-19 pandemic, APRICOT 2021 has moved on-line. It will still be hosted, as planned, by PhNOG, the Philippine Network Operator Group. The new format means a reduction in the schedule but retaining the high quality and high relevancy of the content offered over the years. The APRICOT 2021 Programme Committee is responsible for the solicitation and selection of suitable presentation and tutorial content for the APRICOT 2021 conference (https://2021.apricot.net/) The APRICOT PC Chairs are now seeking nominations from the community to join the APRICOT 2021 PC to assist with the development of the programme for APRICOT 2021. Eligible PC candidates are those who have attended APRICOT conferences in the recent past, have broad technical knowledge of Internet operations, and have reasonable familiarity with the format of APRICOT conferences. Having constructive opinions and ideas about how the programme content might be improved is of high value too. PC members are expected to work actively to solicit content and review submissions for technical merit. The PC meets by conference call, weekly in frequency during the three months prior to APRICOT. If you are interested in joining the PC and meet the above eligibility criteria, please send a brief note to "pc-chairs at apricot.net". The note should include affiliation (if any) and contact details (including e-mail address), and a brief description of why you would make a good addition to the PC. The PC Chairs will accept nominations received by 17:00 UTC+8 on Monday 23rd November 2020, and will announce the new PC shortly thereafter. Many thanks! Mark Tinka, Marijana Novakovic & Philip Smith APRICOT 2021 PC Chairs --

plea for comcast/sprint handoff debug help

tl;dr: comcast: does your 50.242.151.5 westin router receive the announcement of 147.28.0.0/20 from sprint's westin router 144.232.9.61? details: 3130 in the westin announces 147.28.0.0/19 and 147.28.0.0/20 to sprint, ntt, and the six and we want to remove the /19 when we stop announcing the /19, a traceroute to comcast through sprint dies at the handoff from sprint to comcast. r0.sea#traceroute 73.47.196.134 source 147.28.7.1 Type escape sequence to abort.

Bad next-hop? not propagated? covid? magic? which is why we wonder what comcast (50.242.151.5) hears from sprint at that handoff note that, at the minute, both the /19 and the /20 are being announced, as we want things to work. so you will not be able to reproduce. so, comcast, are you receiving the announcement of the /20 from sprint? with a good next-hop? randy

Strange connectivity issue Frontier EVPL
by Jay Hennigan 11 Nov '20

11 Nov '20

We have a strange issue that defies logic. We have a NNI at our POP with Frontier serving as an aggregation circuit with different customers on different VLANs. It's working well to several customers. Bringing up a new customer shows roughly half of the IP addresses unreachable across the link, as if there's some kind of load-balancing or hashing function that's mis-directing half of the traffic. It's consistent, if an address is reachable it's always reachable. If it's not reachable, it's never reachable. Everything ARPs fine. The Frontier circuit is layer 2 so shouldn't care about IP addresses. Frontier tech shows no trouble. They changed the RAD device on-premise. We've triple-checked configurations, torn down and rebuilt subinterface, etc. with no joy. Any suggestions? -- Jay Hennigan - jay(a)west.net Network Engineering - CCIE #7880 503 897-8550 - WB6RDV

Technology risk without safeguards
by Suresh Kalkunte 11 Nov '20

11 Nov '20

Hello, I believe the below described method of causing intentional (1) damage to equipment in data centers and (2) physical injury to a person at the workplace is on-topic for the NANOG community, if not, I look forward to your feedback. As a software developer who has subscribed to the NANOG mailing list for a number of years, I post this note relying on intellectual honesty that I have had the opportunity to observe since 1996-97. The below described technology risk is applicable to computing/communication equipment rendered vulnerable by Intentional Electromagnetic Interference (jamming an electronic device) and the risk of health sabotage affecting people (jamming a human) managing the Internet infrastructure enabled by intentional application of powerful radiofrequency fields (RF) emitted by re-purposed components salvaged from a kitchen heating appliance (Magnetron) or from an outdoor high gain/power Line of sight transceiver (unidirectional microwave radio) which has a harm causing range up to 25 meters (estimated using a Spectral Power Density calculator like www.hintlink.com/power_density.htm) This risk from mis-application of powerful RF is from human operated or IoT apparatus** with an avenue of approch from (a) subterrain placement aided by a compact/mini directional horizontal drilling machine (eg. principle of placing a stent in the heart) and/or (b) strategic placement in an obscure over-surface location to maximize negative impact on the target of opportunity. With building materials or ground offer insufficient* protection to block the passage of powerful RF and the absence of diagnostic/forensic tests to detect biomarkers expressed post-overexposure to harmful RF (combination of RF frequency, Spectral Power Density/Specific Absorption Rate incident on a person and duration of exposure), intentional damage to electronic equipment and people is at present unrestricted. The purpose of bringing this method of exploting technology to your attention is with an interest to build the momentum for ushering in the much needed safeguards in this context. Thanks.

CNAME records in place of A records
by Dovid Bender 09 Nov '20

09 Nov '20

Hi, Sorry if this is a bit OT. Recently several different vendors (in completely different fields) where they white label for us asked us to remove A records that we have going to them and replace them with CNAME records. Is there anything *going around* in the security aranea that has caused this?

Spoofer Report for NANOG for Oct 2020
by CAIDA Spoofer Project 08 Nov '20

08 Nov '20

In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes. This report summarises tests conducted within usa, can.
