Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

My caching nameserver (BIND 9.3.6-P1) cannot contact 216.194.113.11 or 216.194.113.12 over UDP port 53 for some unknown reason. This prevents anyone at my office from resolving names such as phpnet-mirror.tierfour.com. However our nameserver successfully resolves all other names. How can I troubleshoot this issue? Output from dig:

[jnet@Stan ~]$ dig @216.194.113.11 VERSASERVERS.NET

; <<>> DiG 9.4.3-P1 <<>> @216.194.113.11 VERSASERVERS.NET
; (1 server found)
;; global options:  printcmd
;; connection timed out; no servers could be reached

(EDIT: Changed description of the problem, thanks to ko-dos: This is not an issue with *.php.net, it is an issue with the above nameservers specifically)

us2 is a cname for php.he.net. us3 on the other hand is a cname for phpnet-mirror.tierfour.com. These are different SOA and nameservers.

Thank you for that! Sure enough, it's tierfour.com that my nameserver cannot resolve. –  Josh Jul 16 '09 at 14:45
