Description (partial)

 network validation was failing after changing Primary DNS ip address and we
were not able to upgrade subscribers.

Specific error on "utils diagnose test" was:
test - validate_network    : Could not send/receive UDP packets to publisher  
- Is network connection to the publisher up?
- Is the MTU size correct for this network?
- Does the network allow packet fragments?


test - validate_network    : Error, intra-cluster communication is broken,
unable to connect to []                             Error,
intra-cluster communication is broken, unable to connect to []

See attached upgrade-failure-log for upgrade error on subscribers.

 Primary DNS ip address was changed, but no services were restarted.
