Participate in COVID-19 Paper for BITAG? [NANOG]
by Livingood, Jason 24 Jul '20

24 Jul '20

I thought this may be of interest to some of the network operators here on the NANOG list. I am reaching out to solicit interest in participating in the development of a new technical paper from the Broadband Internet Technical Advisory Group (BITAG). In September we will begin work on a short paper that summarizes & memorializes the different sorts of things various players across the Internet ecosystem did in order to react to the unprecedented increase in Internet usage as a result of COVID-19. In the NANOG context, this would be the general sorts of things that access networks, IXPs, transit networks, enterprise networks, etc. undertook to adapt to the huge change stemming from COVID-19. In most cases this is not doing new work but merely referring to already published information, as the goal is to provide a broad survey of actions across the entire Internet ecosystem in order to explain and document the broad arc of the story. Your organization does NOT need to be a member/sponsor of BITAG to participate. As we anticipate the paper being relatively short, the time commitment will be at most 2 hours per week if not significantly less than that (a weekly call plus any text contribution/review). See details at https://github.com/bitag-twg/bitag2.0/blob/master/pandemic-network-performa… I hope you will consider having someone from your organization participate! Please contact Doug Sicker (dsicker(a)bitag.org<mailto:dsicker@bitag.org>) with questions or to participate. Thanks! Jason

Paranoid much? Mehemet is an upstanding guy doing the right thing as well as his site of countless very useful information. But considering this wasn’t even for you ... maybe you have a better solution ? -- J. Hellenthal The fact that there's a highway to Hell but only a stairway to Heaven says a lot about anticipated traffic volume. > On Jul 24, 2020, at 09:51, Tom Hill <tom(a)ninjabadger.net> wrote:

Don Smith, RIP.
by Dobbins, Roland 24 Jul '20

24 Jul '20

It is with a heavy heart that I must relate the news that Don Smith, formerly of CenturyLink and more lately of Netscout Arbor, passed away in his sleep last night. Don was a colleague, friend, and mentor to many; he was a mainstay of the operational community, and tirelessly worked to make the Internet safer and more resilient for us all. His intellect, wit, and generosity of spirit were well-known to those who were privileged to have the opportunity to work with and learn from him. Don’s contributions to the industry were manifold. While we are all diminished by his loss, his legacy abides; and we can honor him by continuing to build upon that foundation, for the betterment of the Internet community as a whole. Once Don’s family have established plans for his memorial, they will be posted here. -------------------------------------------- Roland Dobbins <roland.dobbins(a)netscout.com>

Clever use of a decommissioned Datacenter
by Norman Jester 24 Jul '20

24 Jul '20

I’ve got a fiber rich datacenter that was decommissioned adjacent to One Wilshire. Pipe to coresite and equinix and other fiber as well. The datacenter shuttered due to changing market conditions It wasn’t ready to adapt to. Anyway, wondering if you have any cool ideas on how to raise it up again from scratch. I was thinking renting the whole place out to someone or open to other ideas. Maybe something other than colo? Norman Jester 619-319-7055

Thanks again for this Roland. We have lost one of the giants of the Internet security community. So much of what he did was behind the scenes and without fanfare. From his exceedingly thorough testing of vendor gear to his contributions in the standards community to his ongoing efforts to thwart Internet badness and for me personally his assistance in helping develop various solutions. He was an important and exceptionally helpful partner when we were first developing and rolling out UTRS at Team Cymru. He will be missed. John

Disney+ contacts or geolocation ideas
by Paul Nash 23 Jul '20

23 Jul '20

I’m looking for a technical contact at Disney regarding geo-location. I have a client (apartment building) with a /24 (one IP per apartment). We recently upgraded out Internet connection to give a much-needed speed boost. Same connectivity provider, same IP addresses, just a bigger pipe. Since then, a while bunch of people have been unable to get to Disney+, while some can. Those that fail have existing D+ subscriptions, and get “error code 73”, which allegedly relates to location and rights management. The bandwidth provider has checked DNS, reverse DNS and contacted Disney, to no avail. WhoIS shows it as being in Toronto, Canada. Meanwhile, there is a lynch mob forming, and a scaffold being built in the parking lot :-). Any pointers on how to find someone at Disney with clue, who will be able to tickle their geolocation databane. The really irritating part is that everything worked until we had the bandwidth upgrade.

BFD for long haul circuit
by Harivishnu Abhilash 23 Jul '20

23 Jul '20

Classification:Public Guys, I'm looking for recommendation regarding BFD timers that we can use for long haul circuit. RTT is roughly around 110 ms. In fact this is a l2vpn ckt provided by a telco. Can you please advise the factors we can consider when setting the BFD timers (or any recommended values)? I have set 10 ms dead time but this is causing BFD to go down occasionally.

> Who said anything about boxing your tooling in to SDN tech? You > described Software Defined Networking as a rabbit hole and snake oil. > It isn't. It's a class of tools in the networking toolbox and an > increasingly useful one. My toolbox in the garage has torque wrenches and allen wrenches and a GS-911 for talking to the Motronic on my bike, too. It's a pretty useful toolbox. I use all of them. I don't keep them all in the same drawer of the toolbox, though. Guessing you don't either. Or if you do, I *probably* don't want you working on my bike. I for one would be happy if someone came up with some different acronyms and subdivide the "world of SDN" into some number of sub-techonologies/practices that were at least a little more cohesive with each other so then at least we'd know what keywords to fit into our news feeds so we could pay better attention to the bits that are more relevant to where we are. Ansible/netmiko/<whatevertoolset>+CI/CD applied to kit (and people) does not resemble OpenDaylight or what hyperscalers are doing with DPDK on cards or the Microsoft FPGA-NIC trickery except in the broadest of views. All are good. Sure, they all belong in the toolbox. But maybe not in the same drawer. As it is, we have marketing people sticking "SDN" onto every bloody thing that comes along in the hopes that it'll better catch the attention of someone without enough of a clue that they'll cough up (and leave someone else to figure out what to do with it). I freely admit that's just what they do and expecting them to do anything different is wishful thinking, but I don't see any of us doing anything about it except creating long email chains wherein we just keep trying to munge apples and oranges together. :) -bacon
