Tomorrow I'll be moving the grid engine master node to a new virt host.
That will cause a 15-minute outage during which new jobs (crons, or
things submitted by hand) will fail.
Existing jobs or webservices will be unaffected by the downtime.
I'll start the move at 16:00 UTC on Friday, 2018-12-21. That's 8AM in
California.
