So it appears that my post about home-built speaker stands has been featured on Make Magazine’s blog. The sudden inrush of traffic was so dramatic that it overwhelmed my server before my monit alarms could even go off. Apache spawned a shit-ton of connections, MySQL was overwhelmed, and quite quickly my whole blog went down. My box hit a 1-minute load level of around 80-90 before it finally stopped responding to connections.
Fortunately through monit’s web interface I was eventually able to bring Apache down for long enough to get sshd back up. I managed to log onto my box and drop in wp-cache-2, an excellent Wordpress plugin that automatically caches your posts. 5 minutes later my blog was up and running and it’s now humming around at a much more reasonable level.
