Are you worried that you can’t access your Facebook profile and seeing an error like,
Your account is temporarily unavailable due to site maintenance. It should be available again within a few hours. We apologize for the inconvenience
Your account is currently unavailable due to a site issue. We expect this to be resolved shortly. Please try again in a few minutes.
If your Facebook account is not available and you are seeing any of the above messages when you open Facebook, than there is nothing to worry.
As the messages say, your Facebook account is temporarily unavailable because either Facebook is doing some site maintenance, or it is facing bandwidth issues. In any case, your Facebook profile should be up and running within an hour or less.
If you can’t access your Facebook profile even after an hour, then ask around to your local friends if they can open their Facebook accounts. If they can’t then probably its a bigger site maintenance task, so try again after some time.
However, if all your local friends can open their Facebook profile and only you are seeing the Facebook Account Temporarily Unavailable message, then try clearing your browser’s cache and cookies to fix the issue.
If your Facebook profile is still unavailable after many days, then send an email to email@example.com, firstname.lastname@example.org or email@example.com and explain them the issue. Once you send them an email, your account will be available again soon.
