The NPLB server IP address changed about 3 hours ago. The server's DNS updater correctly updated the DNS reference with the domain host within an hour.

However, the global DNS cache updates are taking some time to cascade - they can take 3 to 4 hours. As a result some of you may be experiencing connection issues.

These issues should be resolved automatically within the next 2 hours.
I am monitoring the update and will confirm when resolved.

RESOLVED:

NPLB server connectivity confirmed fixed by the automated processes in place.
I have made an optimal adjustment to reduce the minimum length of time required to complete the change from 3 hours down to 1.5 hours, for next time. ***

I have been monitoring the logs hourly since Nov-2013 to confirm this change-over. (see post on previous page).
Now that the process has proven itself, admin log-file and connectivity monitoring will return to daily.

Thank you for your patience.

AMDave

(*** allowing for S.T.P., how many fingers you can cross and whether I am monitoring the change at the time or not :P )

Thank you for the excellent work Dave! You have been indispensible on this project. This of course happened while I was out of town and so I could not have dealt with it until next week.

You are most welcome.

The server appears offline - for me anyway.
Investigating.

Unplanned NPLB server outage.

Unable to connect to the server.
Not a DNS issue. The IP address has not changed.
It may be a local power fault.
Requires attention from gd_barnes.
