Major System Update Scheduled
January 8, 2008
On Tuesday, Jan. 8, at 7pm Pacific time, we’ll be undertaking a major technical upgrade of our hosting platform:
- Red Hat 9 → CentOS 4
- PHP 4 → PHP 5
- MySQL 4 → MySQL 5
We anticipate up to an hour of downtime, though it should be less than that total. The upgrade will be handled by an automated script, painstakingly written and watched over by our rockin’ datacenter. The process is well-tested and we do not anticipate any major issues, though it’s possible some minor things may crop up. Please let us know immediately if anything’s not working for you after the upgrade.
Update: The operating system upgrade went extremely well; downtime was less than 30 minutes. We had a few loose ends to tie up: Missing Smarty libs, some SSL issues, but everything’s getting ironed out quickly. SSL email on gong.birdhouse.org may not be fixed before morning.
SpamAssassin kept running, but the setting that enables SA for each user automatically had not made it across the migration. Spam was allowed through the system during this period. Spam settings were re-enabled a couple of hours after the migration was completed.
Unfortunately, the PHP / Apache / MySQL upgrades may have to wait for another day. We’re still running the previous AMP stack, and will tackle this portion of the upgrade soon.
Update 2: SSL certs for POP/IMAP access are working again, and we’ve ironed out all known issues (all were fairly minor; most users didn’t notice that anything had changed).
We’ll post an update on the AMP upgrade plans soon.
