[gembud] 20141107: impending power down and potential service interruptions

Unidata Users:

Tomorrow (Saturday, November 8) at 6 am MST, scheduled maintenance in
two computer rooms where Unidata hosts a variety of community-facing
services will begin and last between 12 and 54 hours.  We have implemented
failover procedures that are intended to minimize or negate service
outages, but there is a chance that the backup systems, which will be
running off of unconditioned wall power, could be knocked offline by a
utility power outage.

Services that may/will be interrupted are:
