Site infrastructure

 * Data Centers —


 * Media Storage — February saw Swift deployed to production to serve thumbnail requests 3 weeks earlier than anticipated.  There were a few bugs that we fixed, but overall the deploy process went very smoothly.  Graphs of Swift's performance are in ganglia.  The next steps are doing some more work around documentation and maintenance procedures, then creating a mirror cluster in Eqiad.  Swift in Labs and original media in Swift are also on the road map.

Backups and data archives

 * Data Dumps — We now have a copy of all dumps on a secondary host in another data center.  We've been working with two organizations on full mirrors of the dumps, sorting out performance issues before they can go live.  Christian (QChris) has got the beginning of a rough test framework for the dumps working.  We've made contact with folks at the Internet Archive and we're working on scripts using the S3 api to push our historical dump archive to their servers.  The source code has been moved to our git repo, and we're in the middle of the transition to MW 1.19, checking that the dumps work correctly for migrated projects.
