Brief MySQL load problems (resolved)

Posted April 7th, 2011 in System Status. Tags: , .

We had a couple of instances of MySQL queries overloading the bender server today. The first one happened at about 3:41 AM (Pacific time) and the second one happened at about 7:48 AM. Each occurrence lasted about 20 minutes. The problem each time was that a database was running extremely inefficient queries. Each time we fixed the problem by creating indexes so that the queries could then run in a fraction of the time previously required.

We apologize for any inconvenience caused by this problem. Visitors to your Web site (on the bender server) might have seen reduced performance (or, in rare cases, 503 errors). E-mail was not affected. We don’t consider this type of problem to be acceptable. These problems should not recur since the indexes have been created.
