Venmo - Geolocation Challenges
by Justin Krejci 23 Apr '20

23 Apr '20

Hello, I am looking for a Venmo network contact that can assist with a geolocation error in their systems. We have customers on a particular IP prefix who are being flagged by Venmo as outside of the USA but they are not outside of the USA. All standard geolocation systems I can find, as well as ARIN, all show the IP prefix as within the USA. Normal Venmo support channels are not fruitful to resolve the issue, they mostly just indicated users need to use their mobile data connection to get a different IP address for Venmo transactions. That is fine as a temporary work around but that is not a solution. Venmo support has expressed they are not going to do anything more for us in this regard. So if anyone has a relevant contact I might reach out to at Venmo or knows if Venmo uses a particular 3rd party geolocation data set and can share that with me that would be appreciated. I don't mind working with any organization to straighten out any stale data, I just need some assistance getting to someone who has the info or access. Thanks!! Justin Krejci

"Is BGP safe yet?" test
by Andrey Kostin 23 Apr '20

23 Apr '20

Hi Nanog list, Would be interesting to hear your opinion on this: https://isbgpsafeyet.com/ We have cases when residential customers ask support "why is your service isn't safe?" pointing to that article. It's difficult to answer correctly considering that the asking person usually doesn't know what BGP is and what it's used for, save for understanding it's function, design and possible misuses. IMO, on one hand it promotes and is aimed to push RPKI deployment, on the other hand is this a proper way for it? How ethical is to claim other market players unsafe, considering that scope of possible impact of not implementing it has completely different scale for a small stub network and big transit provider? Kind regards, Andrey

Are underground utility markers essential workers?
by Sean Donelan 22 Apr '20

22 Apr '20

Utility markers don't get the recognition they deserve. If they aren't essential workers, they should be.... and get hazard pay. They help protect everyone's fiber and cables and pipes that go boom.

Construction crew hits underground fiber line, causes outage of 'call before you dig' hotline

https://www.9news.com/article/news/local/fiber-line-damage-colorado-811-out… Construction crew hits underground fiber line, causes outage of 'call before you dig' hotline Through the 811 hotline you can call to have utility lines marked before doing any digging. DENVER — It looks like someone may have forgotten to call before they started digging and now others are unable to do so due to an outage of the Colorado 811 hotline caused by a busted fiber line. A message on the Colorado 811 website says there's an outage in the communication system. It says an underground fiber line was damaged and it's causing "significant" outages in the Denver area. Construction activity caused underground damage, according to the website. Crews are working to repair the damage, but repairs are not expected to be completed until around 8 p.m. Tuesday. [...]

Enforcement Bureau requests interested consortia to file Letters of Intent to conduct private traceback efforts pursuant to section 13(d) of the TRACED Act https://www.fcc.gov/document/eb-requests-letters-intent-traceback-consortium The Pallone-Thune Telephone Robocall Abuse Criminal Enforcement and Deterrence Act (TRACED Act) was signed into law on December 30, 2019. Congress required the Federal Communications Commission, not later than 90 days after that date, to “issue rules to establish a registration process for the registration of a single consortium that conducts private-led efforts to trace back the origin of suspected unlawful robocalls.” The Commission adopted rules to require any consortium that seeks to be selected as the single registered consortium to file a Letter of Intent to conduct private traceback efforts and directed the Enforcement Bureau to issue a public notice to that effect no later than April 28th each year.

Re: IS-IS Error (FRR)
by Mark Tinka 20 Apr '20

20 Apr '20

So we've been discussing this on Slack. It seems the packet handlers for IS-IS in FRR and how they work on FreeBSD is not completely optimized (not an issue on Linux). FRR-based IS-IS on FreeBSD is sending PSNP's that are 6,020 bytes large. However, FreeBSD's BPF (Berkeley Packet Filter) has a packet data limit of 4,096 bytes. This is what is causing the error. While it is possible to set the IIH MTU in FRR with the "lsp-mtu" command, there is not way to set the PSNP MTU. In short, IS-IS on FRR does not understand that there is an MTU limit for PSNP's on FreeBSD. I'm working with the IS-IS FRR team, but as of now, no idea on if/when there will be a fix for this. While routes are being successfully exchanged between FRR and Cisco IOS XE for IS-IS, this is a show-stopper! So for the moment, I cannot recommend anyone runs IS-IS on FRR in production. As it stands, it appears that this is the only thing standing in the way of a successful deployment, as far as simple Anycast services go. Will keep you all posted as this develops. Mark.
