Hi,
Is anyone from Facebook here? We have huge issues resolving Facebook domains
from some of our customers in The Netherlands and Belgium.
>From our own networks we note that some Facebook servers are indeed dropping
queries over IPv4:
$ dig -4 star-mini.c10r.facebook.com @a.ns.c10r.facebook.com +tries=1
; <<>> DiG 9.10.3-P4-Ubuntu <<>> -4 star-mini.c10r.facebook.com @a.ns.c10r.facebook.com +tries=1
;; global options: +cmd
;; connection timed out; no servers could be reached
We are tempted to deploy workarounds to serve old data.
http://downdetector.com/status/facebook/map/ actually has a pretty map
describing the problem right now.
If anyone from Facebook wants us to try things, please let us know.
Bert
