[outages] Google 8.8.8.8 Resolution of Route53 domains

[Phil Lavin]

In fact, 3 of 4 nameservers on our main domain are advertised as different /24s by AS 10297. None of these can be queried. The other is advertised by AS 16509 (AWS) – this works.

This doesn’t feel right, though I’ll admit I’ve never checked before. Our only route to ns-163.awsdns-20.com (205.251.192.163) is through HE:
inet.0: 757581 destinations, 2107440 routes (757301 active, 0 holddown, 522 hidden)
+ = Active Route, - = Last Active, * = Both
205.251.192.0/24   *[BGP/170] 01:12:08, localpref 70
                      AS path: 6939 10297 I, validation-state: unverified
                    > to 216.66.90.21 via ge-1/0/5.0
AS10297 is eNET inc. Is this expected?

Looks more specific to AWS than it does to Google+AWS. Can’t resolve against some of AWS’s NS directly:
phil at phil-debian:~$ dig cloudcall.com IN A @ns-163.awsdns-20.com
; <<>> DiG 9.10.3-P4-Debian <<>> cloudcall.com IN A @ns-163.awsdns-20.com
;; global options: +cmd
;; connection timed out; no servers could be reached

Yeh. Still digging into it.

Anyone else seeing SERVFAIL for route53-hosted domains trying to resolve with Google DNS?
