CISA critical infrastructure letters
by Sean Donelan 25 Mar '20

25 Mar '20

The CISA critical infrastructure letters are a courtesy request letter. If people abuse its purpose, local officials do not need to extend any courtesy and can deny access. The CISA letter is only for "providing emergency communications sustainment and restoration support to critical communications infrastructure facilities." It is NOT a general purpose, ignore anything or go anywhere letter. Do NOT abuse the courtesy or no one will extend the courtesy.

I got these. One each for travel and fuel. I could fake one in 15 minutes or so. Heck, I could probable find one online and modify it in less time than that! Because of that I don't see the usefulness. scott

Thanks, my facepalm moment of the day (so far; it's only 7:30am here) is... Use tools from the past when the connections everywhere were losy and slow. They already mentioned RT. I'll mention that and NNTP/UUCP/etc. scott

interesting troubleshooting
by Nimrod Levy 24 Mar '20

24 Mar '20

I just ran into an issue that I thought was worth sharing with the NANOG community. With recently increased visibility on keeping the Internet running smoothly, I thought that sharing this small experience could benefit everyone. I was contacted by my NOC to investigate a LAG that was not distributing traffic evenly among the members to the point where one member was congested while the utilization on the LAG was reasonably low. Looking at my netflow data, I was able to confirm that this was caused by a single large flow of ESP traffic. Fortunately, I was able to shift this flow to another path that had enough headroom available so that the flow could be accommodated on a single member link. With the increase in remote workers and VPN traffic that won't hash across multiple paths, I thought this anecdote might help someone else track down a problem that might not be so obvious. Please take this message in the spirit in which it was intended and refrain from the snarky "just upgrade you links" comments. -- Nimrod

Re: COVID-19 vs. our Networks

Seems arbitrary. Lots of networks have lots of Netflix/etc capacity. Who determines what is "mission critical"? Our mission as an ISP is to deliver Internet to our customers. If they want to play online games or watch video, who am I to say that isn't critical to THEIR mission? The last thing we need are a bunch of kids in quarantine that have NOTHING to do because Mike Bolitho thinks their entertainment isn't part of the "mission" of the Internet. About the only thing that might be useful is something to smooth out the big jumps in utilization on game releases - but even that is something that can be managed by adding capacity.

Fwd: Internet operations during pandemics

Did other folk on nanog-l see the nLnog-l note copied here? I wonder how folk are planning for things (noted in the slides) o supply chain for parts/equipment Wait, I can't get me a new shiny shipped because what?? o ongoing rollout of new equipment I'm deploying next week in KIX, I'm currently in LAX how do I get there? equipment arrives.. in between...oops! o noc/etc support staff omg.. wait, I can't have my noc staff in the same room? our 'wfh' solution is ... wait, where is that? how do i get their phone queue sent to them? omg :( <sadness!> o services capacity crunches I love my shiny new dns service.. .wait, why is there a smoking hole where my dns servers were? I think some of this has been discussed (shifts in peaks, leveling of peaks) Some hasn't really... I expect that at least sharing some 'err, our WFH changed now we do: X, Y , Z and use M to get N solved' could be super cool to discuss/share and iterate for better solutions for all of our users. thoughts? :) thanks! -chris (note all the hard work in this message is not mine... thanks Job!) ---------- Forwarded message --------- From: Job Snijders <job(a)ntt.net> Date: Wed, Mar 18, 2020 at 6:02 PM Subject: Internet operations during pandemics To: <nlnog(a)nlnog.net> Dear all, I threw together a slidedeck today on the potential impact and second order effects of COVID-19 on Internet network operations. http://instituut.net/~job/netops_during_pandemics.pdf I hope we together over time can add and extend projections in the deck on what will happen and how we can mitigate the negative effects on Internet operations. We have to answer questions such as: 1) what problems already exist today because of a few weeks of C19? 2) What problems are still coming? Will those be localized or globally? 3) What possible workarounds can we plan for those problems? I would appreciate feedback, comments, corrections or whatever you want to tell me. None of us have been in this situation before, so my guess is as good as yours. Kind regards, Job

Sunday traffic curiosity
by Andy Ringsmuth 23 Mar '20

23 Mar '20

Fellow NANOGers, Not a big deal by any means, but for those of you who have traffic data, I’m curious what Sunday morning looked like as compared to other Sundays. Sure, Netflix and similar companies have no doubt seen traffic increase, but I’m wondering if an influx of church service streaming was substantial enough to cause a noticeable traffic increase. We livestream our services and have been for about a year or so, but normally average just a handful of viewers. Today, we were around 150 watching live. ---- Andy Ringsmuth andy(a)andyring.com
