NANOG Community, I am excited to announce the official NANOG Discord! Everyone can join by visiting https://discord.nanog.org<https://discord.nanog.org/>. In the Discord, you will find groups of channels related to the conferences, NANOG committees, technology (#bgp, #hardware, #ix, and more), and official + unofficial affinity groups. There is also a voice channel to communicate in real-time via audio, video, and screenshare. When you join, please read the #welcome and #rules channels, and tell us a little bit about yourself in the #general channel. Discord roles can be requested in the #role-request channel by providing your name, and letting us know if you are either a NANOG member, a committee member, board member, or staff. While it is not a requirement, we highly recommend you set your Discord Server Nickname to your First and Last Name, and (optional) include your AS number and/or business name (example “Ryan Hamel - Zayo (AS6461)”) to help members of the community find you. The Discord is managed and moderated by the newly formed Moderation Committee (https://nanog.org/about/who-we-are/committees/moderation-committee/) using similar guidelines to the mailing list which also includes the Code of Conduct (https://nanog.org/about/code-conduct/) If you have any feedback or questions about the NANOG Discord, please let us know! Kind regards, Ryan Hamel

DNSSEC & WIldcards
by Dennis Burgess 01 Feb '25

Issues connecting to Cloudflare over IPv4 in Nashville
by Landy Bible 31 Jan '25

31 Jan '25

A client reported issues connecting to various websites this evening and I've narrowed it down to cloudflare hosted sites specifically on ipv4. My traceroutes go through my upstream all the way to Comcast in Nashville where they die. IPv6 cloudflare addresses work just fine, but several v4 addresses I tested fail. Is anybody else seeing similar issues, or anybody from cloudflare here able to help me troubleshoot? Thanks! Landy

Akamai contact | access denied to ups.com
by Vinny Abello 31 Jan '25

31 Jan '25

Hello folks, Are there any kind Akamai contacts that could contact me off list relating to random access denied issues reaching ups.com from my network? Naturally, I have no idea how to reach someone at UPS that is in charge of their web site, but I'll happily take a contact from there instead. We recently started announcing our own address space from our own ASN. I don't know if this problem coincides with that, but it's quite possible. It's intermittent, however. Here's a reference ID from one of the access denied messages. Reference #18.66a6d017.1738338236.f99e2bd TIA -Vinny

Big bump in SE USA?
by Alex Buie 30 Jan '25

30 Jan '25

Hi NANOG, We saw a pretty big bump today in our SE USA footprint (POP is in Lithia Springs/Atlanta Metro) - for about 40 minutes significantly reduced traffic flows from all three of our primary upstreams. You can see it in the "valley" in the below Cacti graphs. We saw broad swaths of the southeastern US (greater Alabama/Georgia/Florida region) affected with an increase in errors and fail-open of a portion of our SD-WAN footprint And here's an example from the SD-WAN telemetry of an affected customer site - and this is un-tunneled trying to reach AWS and our datacenter infrastructure. Curious if any other operators in the region saw or felt this netquake? Alex
