Subject: [outages] Google DNS Trouble

Anyone else having Google DNS problems? Google DNS appears to be very,
very spotty from our site. Coming from prefix 69.36.128.0/20. I can ping
the IPs, but DNS lookups mostly timeout. Haven't been able to replicate
from other sites/prefixes. Haven't been able to find a service status
page for it either.

$ dig @8.8.8.8 google.com

; <<>> DiG 9.9.0 <<>> @8.8.8.8 google.com ; (1 server found) ;; global
options: +cmd ;; connection timed out; no servers could be reached

$ tracert 8.8.8.8

Tracing route to google-public-dns-a.google.com [8.8.8.8] over a maximum
of 30 hops:
