As for the DNS, we have local DNS server inside our LAN that is used by 95% of the machines. This server uses our provider's servers as well as google's: forwarders { 8.8.8.8; 196.3.81.5; 196.3.81.132; }; Our users are just driving me crazy with calls regarding facebook: "is slow", "doesn't work", and a lot other complaints...Occasionally you will find that Google DNS servers get "poisoned" and take you to a non local facebook page. I guess run dig against specific servers and be sure you are ending up on a server which doesn't have some massive ping to it? I spent a while debugging a similar problem where the BBC home page got suddenly slow on me because I was being redirected to some german akamai site rather than the UK one... This is likely to make a difference between snappy and sluggish though, not "dead"...
Let me remove google's DNS and continue testing Facebook sluggishness. Thanks for replying.
Good luck Ed W
