Internal Network Problems Slow Flickr

Flickr is having performance problems due to "massive internal network problems at the primary Flickr data center."

The hugely popular Flickr photo sharing service is experiencing some problems with its web site this evening. From the official Flickr blog: "We're experiencing massive internal network problems at the primary Flickr data center. You may notice this with occasional pageviews (or, at times, most pageviews) taking *much* longer to come across the wire. Oddly, they either take the usual 0.2-0.5 seconds per page or exactly 3, 5, 9 or 21 seconds. We have engineers and network ops people running around like howler monkeys trying to diagnose and fix this, but in the meantime, we all suffer."

UPDATE: "It turned out to be that we had the do_not_work flag set on some of the database clusters." That'll do it.
