from the hot-upgrading-database-servers-ftw dept.
Earlier today, we ran an article detailing that Oracle released 270 critical security updates for many of its products, including MySQL cluster which we use here to provide high uptime and reliability for SoylentNews. Needless to say, it was time to upgrade both NDB backends, and the four MySQLd frontends. While the upgrade did not go completely smoothly due to the fact that MySQL strict mode got enabled, and broke the site briefly, our total downtime was less than five minutes or so. Right now, we had to do a full flush and purge of all caches, which means the site is running a bit larky until they can repopulate but I'm pleased to announce we're up to date and secure!

If you notice any unusual breakages or slowdowns, please let me know in the comments. Otherwise, keep calm and carry on!

Most people familiar with the history know this, but it was a good reminder when the guy going nuts trying to stop him confronted him on the roof and Hitler pointed out, "All those people voted for me. They voted for me."
