I've recently updated to wordpress 3.3. Everything went fine, error free. However from time to time it keeps displaying the following error:
Service Temporarily Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Additionally, a 503 Service Temporarily Unavailable error was encountered while trying to use an ErrorDocument to handle the request.
