On a related note, I recently noticed Google became reachable again over IPv6 from Cogent (I didn't have any automated testing in place so this can well have happened long ago - last posts I can find about the issue are from mid-2020).
It's apparently through Tata/6453 so looks like they figured it out. Does anyone have context on when / how this was done? Can't find anything on the internet! >From Cogent's LG: 6453 15169 2001:550:0:1000::261c:143 (metric 102020) from 2001:550:0:1000::261c:153 (38.28.1.67) Origin IGP, metric 4294967294, localpref 100, valid, internal, best, group-best Received Path ID 0, Local Path ID 1, version 175370 Community: 174:11401 174:20666 174:21100 174:22005 Originator: 38.28.1.67, Cluster list: 38.28.1.83 On 13/11/2023 20:38, Ryan Hamel wrote: Matt, Why would HE hijack Cogent's IP space?

Might irritate Cogent, but its not more "bad" than Cogent failing to uphold the requirements for running a root server.
