Twitter routing contact
by bobp＠purdon.id.au 26 Apr '21

26 Apr '21

Hi All, Is there anyone out there from the routing team at Twitter that could get in touch to look at some sub-optimal routing we're seeing? We've tried the Peeringdb contacts with no success. Cheers, Bob. (AS38195)

DOD prefixes and AS8003 / GRSCORP
by Siyuan Miao 26 Apr '21

26 Apr '21

Hi Folks, Just noticed that almost all DOD prefixes (7.0.0.0/8,11.0.0.0/8,22.0.0.0/8 and bunch of /22s) are now announced under AS8003 (GRSCORP) which was just formed a few months ago. It looks so suspicious. Does anyone know if it's authorized? Regards, Siyuan

Cogent RPKI invalid filtering
by Robert Blayzor 26 Apr '21

26 Apr '21

According to Cloudflares isbgpsafeyet.com, Cogent has been considered "safe" and is filtering invalids. But I have found that to be untrue (mostly). It appears that some days they filter IPv4, sometimes not, and IPv6 invalids are always coming through. I know it's Cogent, but curious as to what others are seeing. invalid.rpki.cloudflare.com has address 103.21.244.15 invalid.rpki.cloudflare.com has address 103.21.244.14 invalid.rpki.cloudflare.com has IPv6 address 2606:4700:7000::6715:f40e invalid.rpki.cloudflare.com has IPv6 address 2606:4700:7000::6715:f40f BGP routing table entry for 103.21.244.0/24 174 13335, (aggregated by 13335 172.69.172.1) Origin IGP, metric 83040, localpref 100, valid, external, best, group-best, import-candidate Community: 174:21101 174:22012 BGP routing table entry for 2606:4700:7000::/48 174 13335, (aggregated by 13335 172.69.172.1) 2001:550:2f01:: from 2001:550:2f01:: (66.28.1.115) Origin IGP, metric 83040, localpref 100, valid, external, best, group-best, import-candidate Received Path ID 0, Local Path ID 1, version 1272502628 Community: 174:21101 174:22012 -- inoc.net!rblayzor XMPP: rblayzor.AT.inoc.net PGP: https://pgp.inoc.net/rblayzor/

RE: BGP and The zero window edge
by Jakob Heitz (jheitz) 25 Apr '21

25 Apr '21

Ben's blog details an experiment in which he advertises routes and then withdraws them, but some of them remain stuck for days. I'd like to get to the bottom of this problem. Has anyone else seen this before or can provide data to analyze? On or off list. Regards, Jakob. -----Original Message----- Date: Wed, 21 Apr 2021 07:31:10 -0400 From: "Jean St-Laurent" <jean(a)ddostest.me> Nice article explaining a specific BGP corner case not removing routes when TCP window reaches 0. https://blog.benjojo.co.uk/post/bgp-stuck-routes-tcp-zero-window The proposed solution is a new RFC for BGP with the suggestion to introduce a new timer.

OOB management options @ 60 Hudson & 1 Summer
by Matthew Crocker 25 Apr '21

25 Apr '21

I have routers in both 60 Hudson St & 1 Summer St and I’m looking for some low cost bandwidth options for out of band management. Currently I have Opengear boxes at each site with cell modems but they don’t work too well. I either need to replace them with new cell based devices or find a wireless/ethernet bandwidth option. I only need a couple serial ports and ethernet for when everything breaks. I’m in DR space @ 60 Hudson and the Markeley MMR @ 1 Summer I’m surprised OOB bandwidth isn’t a feature for colocation providers. Thanks

FCC fines for unauthorized carrier changes and consumer billing
by Sean Donelan 23 Apr '21

23 Apr '21

The FCC has a poor record of actually collecting money from Notices of Apparent Liability (i.e. fines). There are flaws in the FCC notification rules, but it does have some rules requiring indpendent verification of carrier changes. FCC Fines Tele Circuit $4,145,000 for Cramming & Slamming Violations https://www.fcc.gov/document/fcc-fines-tele-circuit-4145000-cramming-slammi… FCC fines Tele Circuit Network Corporation $4,145,000 for switching consumers from their preferred carrier to Tele Circuit without permission and adding unauthorized charges to consumers' bill In this Order, the Federal Communications Commission (FCC or Commission) adopts the findings in the Notice of Apparent Liability (Tele Circuit Notice or Notice) that Tele Circuit Network Corporation (Tele Circuit or Company) engaged in slamming and cramming, made misrepresentations to consumers, and violated a Commission order by failing to produce certain information and documents relating to the Company’s business practices. The Company’s misconduct harmed elderly and infirm consumers, in some cases leaving them without telephone service for extended periods of time—with Tele Circuit refusing to reinstate service until the crammed charges were paid in full. These practices violated sections 201(b) and 258 of the Communications Act of 1934, as amended (the Act), and section 64.1120 of the Commission’s rules. After reviewing Tele Circuit’s response to the Notice, we decline to find that the Company violated section 1.17(a)(2) of the Commission’s rules and reduce the proposed penalty by $1,178,322, and therefore impose a forfeiture of $4,145,000. [...] In particular, Tele Circuit did not provide proof that the complainants listed in the LOI authorized Tele Circuit to switch their long distance carrier. In response to the LOI, Tele Circuit did produce some third-party verification recordings,31 which are supposed to provide evidence that customers assented to changing their long distance service from their existing carriers to Tele Circuit. However, some complainants who listened to the recordings alleged that the third-party verifications were falsified. In all, the Bureau reviewed more than 100 written consumer complaints, contacted numerous complainants, obtained substantial documentary evidence (including copies of consumer telephone bills), listened to third-partyverification recordings, and received data from consumers’ carriers. [...] Tele Circuit switched the telephone service of 24 consumers without verified authorization to do so, in violation of section 258 of the Act and section 64.1120 of the Commission’s rules. [...]

Submitting Fake Geolocation for blocks to Data Brokers and RIRs
by nanoguser100 23 Apr '21

23 Apr '21

I wanted to get the communities' opinion on this. I am an admin for a quasi-ISP providing cloud hosted desktop solutions for end users. We have POPs all around the world, own our own ASN, and advertise /24s or /23s at each of our POPs fro our large aggregate. As an ISP we submit our blocks to popular geolocation vendors such as Google, Maxmind, IP2, etc and put the proper geolocations in our RIR records (RADB, ARIN, etc). Increasingly I have run into 'niche needs' where a client has a few users in a country we don't have a POP, say Estonia. This is 'mainly' for localization but also in some cases for compliance (some sites REQUIRE an Estonian IP). With that being said is it common practice to 'fake' Geolocations? In this case the user legitimately lives in Estonia, they just happen to be using our cloud service in Germany. I do want to operate in compliance with all the ToS as I don't want to risk our ranges getting blacklisted or the geo vendors stop accepting our data. I would think it's pretty easy to tell given a traceroute would end in Germany even though you're claiming the IP is in Estonia. How common of a practice is it to 'fake' the geos? Is it an acceptable practice? Sent with [ProtonMail](https://protonmail.com) Secure Email.
