Since Saturday night Facebook server is over loaded. It is showing me 404 page saying “The page you requested was not found.” for any valid page links.
This shows that database server is over loaded and down sometimes. Also some updates in news feeds getting blanks. For e.g. some friend became fan of . page.
The issue has been seen on Facebook India account and it may be because of over loaded groups and application requests on Facebook, though there is no official announcement or update on the issue.
Facebook site is taking too much time in loading. There are no news of any kind of attack on the Facebook server. It might be a result of sudden increase in number of active users.
Also some people have been reporting of login problems.
