It says"This domain is blocked. Site

try the mobile site www.m.facebook.com. if you can't get onto the mobile site too it might mean facebook is blocked

firewall, go through firewall or internet security settings and facebook should show up on a list. if you are a a job, some jobs put a firewall block on facebook. try https//www.facebook.com. only thing different is the httpS. very important.

Isn’t the internet great?

Well the way that these filters work is that they look for the EXACT address: www.facebook.com. To fix this you’ll want to add https://www.facebook.com and http://www.facebook.com. This will help the filter to see all combinations and block them all.

Let me know how this turns out!

If you are using an Internet connection supplied by your school or your employer, then they have the right to block "time-wasting" (also known as "social networking") sites.

If you are using your school's network, or your employer's network, then you probably clicked "I Agree" to allow the network administrators to manage the network any way that they want to, including blocking "time-wasting" sites such as Twitter and FaceBook.

A PDF copy of your manual can be found here,,,

http://files.dlink.com.au/products/DI-524/Manuals/DI-524_G2_Manual_3.00.pdf

You want to go to page 26/97 (based on PDF above)

Here you can enter the "domain name" of the site you want to block.

example:

Click "Allow users to access all domains except Blocked Domains".

If you wanted to block "www.xyzzy.com" you would enter "www.xyzzy.com" into the "Blocked Domains" box, then hit "Apply". You enter whatever site you want blocked, no "http://", just the actual name, again, as example, www.xyzzy.com.

You may need to reboot your router after you are finished.

I am the network admin. It's my computer, router, etc... This happened to me, it said "Sorry, but www.facebook.com is blocked on this network."

Open you internet browser options. You can find the sites that were blocked there :D

ping the face book site
that is go to the DOS prompt and type ping www.face book.com this will give give 4 replies back if the site is responding. If not then you have a firewall issue or a DNS (Domain Name service) issue.
Ping this ip 66.220.153.15 if you get the site with this then there is a problem with the DNS.
