[Outages-discussion] [outages] Google 8.8.8.8 Resolution of Route53 domains

[Joseph B]

Issue was resolved around 12:56 UTC when the routes vanished.

These were the only routes that 10297 was advertising via 6939.

Given that AS10297 originates 209.51.192.0/19 and some /24's within that, maybe the cause was bad typing, as well as HE not filtering a peer correctly.

IPv6 capable networks were still able to reach the impacted Route53 hostnames that had aaaa records published.

Cheers,

Joseph
