Hi there!
A local ISP has told us that there's some strange behavior with at least one
node in i.root-servers.net (traceroute shows mostly China)
It seems that when you ask A records for facebook, youtube or twitter, you get
an IP and not the referral for .com
It doesn't happen every time, but we have confirmed this on 4 different
connectivity places (3 in Chile, one in California)
This problem has been reported to Autonomica/Netnod but I don't know if anyone
else is seeing this issue.
This is an example of what are wee seeing:
$ dig @i.root-servers.net www.facebook.com A
; <<>> DiG 9.6.1-P3 <<>> @i.root-servers.net www.facebook.com A
; (1 server found)
;; global options: +cmd
;; Got answer:
