Google is blocking support options and closing tickets on request.
Failed to start VM instance on (machine type) current unavailable on (zone). blah blah.
We switched Zones, switched machine types, but are constantly getting this error.
I wrote a support ticket. They closed it with no response and then closed down my options to file a ticket or call support. Even going so far as removing my option contact sales to get advanced support.
Seems to be something fishy going on with the support system as well as the server status. We've been down for 14-18 days through the past 2-3 months.
