Even without anycast, an ECMP shouldn't hash on the ECN bits. Doing so will split the flow over multiple paths; avoiding that is the whole point of doing the flow-based hashing in the first place. Anycast "only" turns a potential degradation of TCP performance into a hard failure... :) -Toke

Getting Fiber to My Town by Jared Mauch
by Jared Brown 11 Aug '22

11 Aug '22

I believe this belongs here: Getting Fiber to My Town by Jared Mauch https://www.youtube.com/watch?v=ASXJgvy3mEg (YouTube video of NLnog presentation) https://nlnog.net/static/live/nlnog_live_sep_2020_jared.pdf (slides for presentation) https://news.ycombinator.com/item?id=24424910#24430901 (discussion on Hacker News with Jared participating) https://washftth.com/ (project homepage) I find this an interesting description of how to apply skills that we normally only use at work to solve connectivity issues at home. Quite timely too, as home connectivity is needed more than ever. Highlights: - location: just outside of Ann Arbor - no fixed broadband since 2002 -> build own network - pre-wire neighbors with fiber drops and feed them off WISP first - lots of work to sign up customers, having to resort to snailmail to reach all - 70% of homes passed signed up - Have ASN, get IPv6 and IPv4 allocation, multihome and connect to local IXP - purchase equipment: fusion splicer, OTDR, materials, directional drill(!) - hire contractors, deal with all manner of problems, theft, stop work orders, unbudgeted costs, unmarked/badly marked utilities, hitting (own) utilities - build own fiber blower(!) for blowing in fiber in ducts - splice, OTDR, resplice, schedule installs ... which don't always go to plan - Upstream very helpful, offered a Cisco 6500 as CPE, however respectfuly declined and went with Arista - Link up! Network is now live with 17 subscribers hooked up. More waiting to be connected - Mixed Active Ethernet and GPON - latency drops from 30 ms to 8 ms, bandwidth from 20-30M to 730M, total commit 1.5G on 10G port, plans from 50M to 500M - SPAM! IPv4 brokers and the usual unsolicited contacts from bottom of the baller IP transit providers - Costs: $126k in 2020, $95k contractors, $32k materials and equipment. Total outlay ~$150k + years of sweat equity. Important to spread out costs over longer period of time to be able to afford. Offset costs by using pre-pay model (Can pay $5,000 up-front and receive $50 credit for 100 months) All in all it was an excellent presentation. I only wish Jared had spent some more time on how he had to become a telco and how this got him better access to the public right of way. Of course, some more details on his directional boring and some nice video of him running the drill would have been a cherry on top :) I'd like to congratulate Jared on lighting up his network and wish him success in running it. I did a similar build almost twenty years ago and regret I didn't have the forethought to document the effort better then. Not that there was a YouTube to put it all on then :) You can find the other presentations from NLnog live September 2020 at https://www.youtube.com/channel/UCVz78FbsOJ6v6xb6S2GpvWQ Jared, not the Mauch one

DoD IP Space
by Chris Knipe 27 Apr '21

27 Apr '21

Hi Guys, Except for the email on ARIN's details, does anyone else have a contact for the DoD? We are experiencing a situation with a 3rd party (direct peer), wanting to advertise DoD address space to us, and we need to confirm whether they are allowed to do so or not. Range in question is the 22.0.0.0/8 network, which according to ARIN is actively assigned to the DoD (US). -- Regards, Chris Knipe

AWS contact?

20 Feb '21

What is the best avenue for contacting support for AWS? I have several ISPs experiencing reachability issues with AWS hosted sites. These are from different backbones, different gear, etc. The common denominator is AWS. Been googling around and can’t seem to find a contact.

measuring Superbowl traffic
by surfer 28 Jan '21

28 Jan '21

Howdy, I have a request from management to 'measure our Superbowl traffic'. In researching it I found last year they used 4 different CDNs, but I could never find out which ones. Has anyone out there gotten the same request and figured out how to do that this year? Thanks!

MIB Browser Recommendation
by Graham Johnston 27 Jan '21

27 Jan '21

We have historically been a CentOS shop when it comes to choice of Linux OS, and in turn that meant, largely out of laziness, that we used mbrowse to browse mibs and perform simple snmp test queries to devices, just manual work until we find what we want and configure something in our NMS. We are moving some servers to Ubuntu now with the change to CentOS/RHEL, and we are curious what others are using for a SNMP/MIB browser. An FOSS choice would be on top on our list as it is just easy to install from the repo, but I'll take any recommendation that people have. Thanks, Graham

Can someone explain to me what is a half fibre pair? I took it literally to mean a single fibre strand but someone insisted it was a large quantity of spectrum. Please illuminate.

I’m curious how many networks have this as part of their default configuration? If you’re bored on a weekend please click through to this and say yes/no. I’ll summarize in a week or so. If I configured the form right, it should also show you the results as well. https://forms.gle/xxLnA7KgQL48VMNe8 - Jared

unsure if this is allowed or not, but, here goes. https://www.gofundme.com/f/ed-hew-medical-expenses some of you may remember ed. some, maybe not. but, as the uucp maps maintainer for canada, he was quite influential in the rise of email, and to some degree, the internet, in canada. --jim -- Jim Mercer Reptilian Research jim(a)reptiles.org +1 416 410-5633 Life should not be a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside in a cloud of smoke, thoroughly used up, totally worn out, and loudly proclaiming "Wow!

Collaborating Across Continents: A Conversation with Barrie Jones Cook + Toni Yannick Kalombo
by NANOG News 25 Jan '21

25 Jan '21

*“Meeting at the NANOG 80 Hackathon gave us the opportunity to get to know each other over a shared objective.”* We recently spoke with Barrie Jones Cook of San Diego, and Toni Yannick Kalombo of Johannesburg, who not only met via the NANOG 80 Virtual Hackathon, but also formed a team there, and continued to collaborate on their project once the hackathon wrapped. With diverse backgrounds in network and software engineering, and varying levels of hackathon experience, the two were able to combine their particular skills and experience to create a virtual-lab network, with the hopes of establishing a working group so the collaboration can continue well into the future.

Frontier Tampa issues
by Nick Olsen 25 Jan '21

25 Jan '21

Anyone else seeing weird things on Tampa/Bradenton FIOS connections? I've got three unrelated customers that cant establishes IPsec back to me. And a third that can't process credit cards out to their third party merchant. Customers are in 47.196.0.0/14. In All instances, I see the traffic leave the CPE behind the FIOS circuit. The IPSEC traffic never makes it to my DC. And no clue on the credit card traffic. But it goes un-ack'd And just now a fifth has appeared that can't query DNS against 8.8.8.8. Responses go out and never come back. The first four all started around noon today.
