Try <random string>.pfsense.org (see below) to avoid caching, since the problem in question does not rely on the name existing. I am able to reproduce it roughly every 3rd random string I try, definitely not every time. I am unable to reproduce it with other domains so far, only pfsense.org and when it does occur I see a 1500-2200ms query time:
This appears to be a problem with the authoritative servers for pfsense.org. They are dns[1-5].registrar-servers.com (which each have multiple IP addresses). If I try each IP, I get no response from 38.101.213.194 and 2+ second response time from 69.16.244.25. Both of those IPs are listed for dns1.registrar-servers.com. -- Chris Adams <cmadams () hiwaay net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
