Beginning at 12:08AM November 2nd (this morning, not yesterday morning) we began to receive RTMT alerts:
Service status is DOWN. Cisco CAR Web Service. The alert is generated on Mon Nov 02 00:08:24 CST 2009 on node [publisher].
I was unable to get to the network features services page for the publisher, nor was I able to login to the admin pages. I ended up having to restart the server via CLI. Is this possibly some sort of DST bug? It's odd that this happened almost exactly 24 hours after the real DST change occurred.
