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 and 2+ second response time from  Both of
those IPs are listed for dns1.registrar-servers.com.

I don't speak for anybody but myself - that's enough trouble.
