If there is a Facebook server issue, it may be due to a problem or load limit on Facebook's servers.  It can be associated with the entire Facebook site or limited to specific pages.

 If there is a network problem, you may have problems with your Internet connection, which may cause interruptions in Facebook or your Internet flow.

 If the site expires, there may be a problem with Facebook or your device's local storage, or there may be a temporary problem with Facebook's servers.

 In any case, the best way to resolve the issue is to check your internet connection, or contact Facebook's site for assistance with any of the services.
