A while back I posted about an error in the static page generation that took down our database server and what were were doing to make sure it wouldn't happen again.

Well, it worked.

One of the sites seemed like it wasn't generating pages (it was actually a cron job stuck in a loop deleting all the static pages non-stop as soon as they were generated instead of every 20 minutes) and it was serving all dynamic content. But memcached saved us. We were getting over a million memcache hits in less than 4 minutes. So yeah, a million db hits from ONE site (there are many) to a single db server in 4 minutes would definitely have taken it out.

Thank you memcached.
