Re: [cisco-voip] CUCM losing access to NTP for extended period

[Anthony Holloway]

"When a cluster has external NTP clock configured and that clock source is
unavailable for some reason Publisher node will stop synchronizing its
clock with the rest of the cluster nodes. This causes all nodes to drift
independently of each other. This condition could lead to major DB
replication failures that depends on all nodes part of the DB replication
network clocks' to be in sync all the time. Other services such as AMC, or
RISDC could also be impacted due to the clocks being out of sync."

By the way this is a pretty nice little document on NTP.  I've hit that M1
migration bug twice now.

Forwarding this to the list for Lelio:

what happens if our voice servers loose access to ntp servers for a long
period of time?
