Facebook DNS problems


[link to this post]
 
Am a BT customer in Surrey and there seems to be problems with DNS and Facebook.

ping facebook.com gives me 69.63.181.12 works, but when I connect to facebook.com from a web browser it no longer works, I guess some subdomain is having problems resolving.

My DNS are
Primary DNS: 194.72.0.114
Secondary DNS: 194.74.65.69

If I switch to use Google's free DNS service, it works fine

You can also try this list

What I do is pop all the IP addys into notepad like:

@ echo off

ping IP addy -n 10
ping IP addy -n 10
ping IP addy -n 10
ping IP addy -n 10


Save the file as a .bat and run it from command prompt. Spot the most responsive and set that as you DNS server.

Message to the mods:

Don't you hate it that you can't disable sigs? Ha Ha!
