"Please try again. We apologize for any inconvenience."
If you need to open a case, and you receive an error response twice in 5 minutes, then wait on hold for 15 minutes... what are the options? Beyond hang up, attend to issues then try again short while later. 11.5 update brought much chaos. 11.5.2 seemed to keep gremlins at bay. They would jump out of the closet occasionally. Today, is a very bad day.
