How do I diagnose not being able to reach a specific website as an end user?
My country has filtered Facebook. When I use ping www.facebook.com
, all packets are received correctly, but when I browse to http://www.facebook.com/, I can't see the Facebook site and I'm forwarded to another page. How can I fix this problem?

The other sites also ...

when you ping DNS hostnames, ping network packets are transmitted as ICMP. but when you visit it as a web site, it is using HTTP, which utilises port 80 or port 443 if on SSL. ICMP may not be blocked, but port 80/443 are. – icelava – 2011-02-16T10:40:12.677

Your forwarded to another site? try pinging facebook.com, see what IP the name resolves to, enter that IP. It may bring you to the site you were redirected to, this will indicate the use of DNS filtering, I can see this as the easy way to block site ALOT of sites. It resolves to http://69.63.181.12/ in states try connecting to that IP it will at least give us more info about how they are blocking access to facebook.
