Quick summary: I just got back from the 221 data center (gee, it’s hot outside) having replaced what we suspect are bad power supplies in a Virtual Machine Host server. We isolated the issue to this specific server rebooting without offering any useful information as to why in its logs, coupled with a bad set …

A similar outage to this morning is occurring (though limited in scope at the moment since we know what *won’t* work to bring things back. Stand by…

Depending on your MMS application, the instructions for doing this may vary. I’ve included instructions for two Google messaging apps. Check the settings in your SMS/MMS app if it’s not one …
