Maybe the problems are not on the authoritative side... All names you mention (which are not strange at all) are gTLDs, they are all bound by ICANN contracts with SLA, including a 100% one on working DNS service, so I really do not believe you will get timeouts from their authoritative nameservers but it is really not clear what you are testing exactly and how. It seems also not very related to modperl at this point and I see you crossposted to the DNS OARC dns-operations mailing-list. -- Patrick Mevzek
