I just thought I should send out a quick update to give everyone an idea how the upgrades are going.

websrv02:
We successfully upgraded websrv02 last night, with little in the way of problems. There was only minimal service interruption (about ~15 minutes), and all services are operating as normal. If your website is on websrv02 and you are having any trouble, please let us know immediately.

websrv01:
We were having some trouble doing adequate backups of websrv01 and we cannot start these major server upgrades until we are satisfied our backups are reliable. Unfortunately we have no real choice but to push the scheduled downtime back until our backup process is complete, which could easily take another 2 or 3 hours.

Please be advised that there will be a service interruption while we are doing the upgrades.
