Facebook error

today the online community site facebook is showed error message when you try to login with correct username and password for few hours.

Facebook which gain number.1 position leaving myspace behind, showed the error

first when tried to enter with username and password but couln't enter but when tried using facebook gmail message, it worked.

but now in current everything is now running well hope we may not see this type of error message again which is usually seen with myspace which show technical error message when you try to get a URL for your profile
