08 Feb '22

In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes. This report summarises tests conducted within usa, can.

If anyone from Cloudflare lurks here, could you please reach out to me directly?

by Rafael Elvira 07 Feb '22

07 Feb '22

Hello everyone, I'm reaching out from the traffic team over at Slack <https://slack.com/>. As many of you might be aware, we had a series of unfortunate attempts to enable DNSSEC on slack.com <https://slack.engineering/what-happened-during-slacks-dnssec-rollout/> last year. We are planning to publish the slack.com DS record at the '.com' zone on Feb 12th at 7AM PST (15:00 UTC). Our authoritative zone and delegated zones are already signed and have their link of the chain of trust all set. If you see any issues with slack.com in your networks after or on Feb 12th we'd be very grateful if you can contact us. Thank you! Rafael Elvira, Slack.

Amazon peering revisited
by Kelly Littlepage 05 Feb '22

05 Feb '22

Hi all, a nanog thread started on November 23, 2018 discussed the challenges of getting Amazon peering sessions turned up. Has anyone had luck since/does anyone have a contact they could refer me to — off-list or otherwise? The process of getting PNI in place with other CSPs was straightforward, but I haven't heard back from AWS after a month and several follow-ups. Our customers would really benefit from us getting this sorted.

Re: AT&T Internet (AS7018) <> Tata Communications (AS6453) daily North-West US coast connection drops
by Tristan 02 Feb '22

02 Feb '22

> I don't know what mail client you use but it turned your message (or > at least the text/plain part) into one unreadable mess of a long line. Argl... thought I'd set it to plain text; clearly not. Sorry. What follows would be the actually-readable version of it... --- Hello, For the past month or so now, we've been observing severe issues affecting our availability to North-West US coast AT&T users when reaching us through Tata communications. It seems to occur daily, from roughly 4:40 AM UTC and until 7:30 AM UTC, and connections get entirely dropped on their way from AT&T to Tata. The issue might be more extensive geographically and or timespan-wise but that's the specifics we've been able to confirm ourselves. Using global traceroute (and specifically probe 3670, AT&T Sacramento), the issue seems to revolve around 12.122.114.5 [AS7018]. Here's an example traceroute of what's happening: traceroute to 203.175.174.246 (203.175.174.246) 64 hops max, 76 byte packets 1 10.0.0.1 (10.0.0.1) [AS???] 8.345 ms 2.064 ms 2.01 ms 2 68.78.72.22 (68.78.72.22) [AS7018] 2.755 ms 2.5789999999999997 ms 3.197 ms 3 * * * 4 71.147.199.98 (71.147.199.98) [AS7018] 20.544 ms 20.274 ms 20.285 ms 5 12.122.160.166 (12.122.160.166) [AS7018] 30.043 ms 28.155 ms 26.833 ms 7 12.122.114.5 (12.122.114.5) [AS7018] 25.962 ms 26.106 ms 26.115 ms 8 * * * 9 * * * 10 * * * 11 * * * 12 * * * 255 * * * Interestingly, the other way around (Tata->AT&T) works just fine, making its way into AT&T's network through 192.205.37.69 this time. We'd hoped things would fix themselves and moved traffic around via other ASNs in the meantime, but it seems that the problem is either not known or at a standstill. Does anyone know something more or experience the same issue? From some unsubstantiated claims I have been given it seems like the issue would be on Tata's side but it's been nothing more than hearsay and a few vague links so far (such as https://mailman.nanog.org/pipermail/nanog/2022-January/217126.html) so I was hoping for something more definitive, or hearing about others encountering similar issues. Thanks, Tristan PS: The target host in the example above is not ours, nor affiliated with us. Please don't bother them about us, they are merely affected in the same exact way as we are.
