DNS servers - just a short comparision ...

Either the DNS servers of my ISP are extremely good or other providers have extremly bad DNS servers. I’ve repeated each request ten times and took the second-best result: Google DNS:

$ dig @8.8.8.8 facebook.com | grep "Query time:"<br />
;; Query time: 31 msec

OpenDNS:

$ dig @208.67.222.222 facebook.com | grep "Query time:"<br />
;; Query time: 44 msec

Telekom T-Home VDSL

$ dig @217.237.150.205 facebook.com | grep "Query time:"<br />
;; Query time: 22 msec
