These are only operating system upgrades and service releases - going
from 4.2 to 4.4.  We have a publisher and subscriber in our main office,
and a subscriber in our second biggest office.  Our third office is an
SRST site.

If the WAN is only connecting remote offices, then you should be okay.
If all your CallManager servers are in the same building you are fine.
Any remote phones will upgrade firmware once the wan is back up.

We are planning to upgrade the base OS and patch one Publisher and two
Subscribers this Saturday night.  All of our building power where our
servers reside will be "on", but our WAN circuits come into our complex
in an adjacent building where the power will be shut down for up to 12
hours.  Assuming that the WAN circuits will be dead, should we go ahead
and load the software or should we wait until the WAN circuits are fully
operational?  We normally load the Pub/reboot and then load the Subs and
reboot after each new piece of software is loaded.  Please let me know
if there can be negative repercussions.  Thank you!
