Please go and read the solution right there.

Hope this helps.

Please check in case you haee blocked the website.

In case you are using internet exploere 7

click on tools -> internet options -> Privacy Tab-> Sites.

Make sure that yahoo is not listed there.

In case you are still not able to access, try clear cookies and cache.

In case still inaccessiable, try a different browser.

Go to your email preferences and find something like "block addresses" and add the site you want to block. Also send them an email to stop the emails. If you are/were signed up for the site, sign in, go to the sites email preferences, and choose accordingly.

If you are positive that you are connected to the internet and you can browse other sites, then the issue would most likely be your Internet Firewall and/or antivirus/antispyware software that is blocking this particular site: you can check by turning off all Internet Firewall, Antivirus and Antispyware softwares. Incidentally, the firewall software can also be active in your modem/router and this would be the issue if you are not running any protection software on your PC/laptop!
If this works, then re-activate your protection software and review the log to see what exception for Facebook is required.
Hope it helps: let me know how you go.

This is definately your parents or someone else putting Security software on your network. This will stop you from viewing sites that the individual has deemed "inapropriate". The problem with this is that people are given the option to block "Web based chat" or "online gaming" and don't pick particular sites. This leads to perfectly fine sites being blocked. You should talk to whoever controls your network. Also use www.ebuddy.com to access your msn if its blocked.

sometimes this happens to me for bebo,
what i did to make it work was type in Bebo Sign In
in Google, then press on it, then it should take you to your page!
if not, i dunno.
