Spoofer Report for NANOG for May 2024
by CAIDA Spoofer Project 08 Jun '24

08 Jun '24

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.

Comcast.net email servers - temporarily blacklisted IP Address errors
by Martin Cook 07 Jun '24

07 Jun '24

Hello NANOG, We recently started getting some complaints from customers experiencing an error when trying to access their old Comcast.net email accounts with one of their email clients (outlook tbird etc.) via POP3 or IMAP. Web based use of their email via the Comcast portal is unaffected. "ERR [AUTH] Temporarily blacklisted IP Address - try again later" These customers are previous Residential HSI subscribers of Comcast who have since moved to other internet service providers, including ours, and are still allowed to use their old email accounts. There is a web portal based method for attempting to get individual IP addresses removed from the "temporary black list". But due to the number of reports we have had in a very short period of time we believe an entire range of IP's (possibly a /17) has been blacklisted as of last Friday-ish We're having difficulty resolving this issue through Comcast customer support or the Comcast Security assurance team. So I'm looking to see if anyone from Comcast or someone who has had this issue before reach out off-list to assist with resolving this headache. **** Enjoy N91 next week for all the people attending, stop by to attend Jason Rokeach's talk on "meshrr: Hierarchical Route Distribution @ Scale w/ Kubernetes on Wednesday!" I'm sure he will have some awesome things to show everyone. Thanks, Martin Cook

West Coast Peering / Packet Loss issues between AS7018 (AT&T) and AS6461
by Alex Buie 05 Jun '24

05 Jun '24

Since roughly 6:30AM local time on Tuesday we have been seeing significantly increased packet loss (20-40%) and latency increase of ~30-40ms from customers on the west coast hosted out of AS7018 (AT&T/sbcglobal) towards our addresses announced through Zayo (AS6461). Has anyone else noticed or seen this? We're working through our channels with the carrier but the latency profile is such that it seems likely it may be affecting others as well and I wanted to ask the group. Any incidents that anyone is aware of which may be related? Thanks, *Alex Buie*Senior Cloud Operations Engineer 450 Century Pkwy # 100 Allen, TX 75013 <https://maps.google.com/?q=450+Century+Pkwy+STE+100+%7C+Allen,+TX+%7C+75013…> D: 469-884-0225 | www.cytracom.com

To those interested , This is an ongoing issue for my users . AT&T and Zayo have not responded to my requests . AS7018 12.122.114.5 AS6461 64.125.12.117 >From June 4 , 2024 , Packet loss continues and has been going on between AT&T and Zayo/ABOVENET all day . According to DNS packet loss appears to be on a lag in SJC7 . ( Evocative San Jose Data Center ? ) According to all traceroutes the IPs on each side of the packet loss are AT&T 12.122.114.5 and ZAYO 64.125.12.117 . When the traceroute confirms the IPs above are in the path ; packet loss to or from any endpoint is greater than 15% . So far I tried reaching out to technical support with both providers via public and standard channels . I’m asking for help passing this information along to AT&T or Zayo hoping the community can provide some assistance to deliver this message because their technical support can not . Please forward this information along if you really do know the right person to ask don’t just spam them with messages . Don’t assume someone else will look at this and forward it to the correct person .

Looking for contact at Microsoft optical networking
by Scott Campbell 05 Jun '24

05 Jun '24

We are looking for a contact within the optical group at Microsoft networking to discuss a fiber outage event in the Chicago area during third party physical maintenance that resulted in accidental information disclosure between our organizations on or around 22 March, 2024. Our intent is to better understand exactly what happened and what can be done to mitigate potential fallout in the event that this happens again. Many thanks, Scott Campbell ESnet Security Tech Lead
