Just a warning folks: later tonight I'll be taking Wikipedia offline for a bit for regular backups, and conversion to a different database table format which should better withstand the heavy peer pressure that a young wiki encounters as it discovers the wonder that is "a whole frigging lot of users".
test.wikipedia.org has been running with InnoDB tables for some while and no one seems to have had any problems with that aspect of it, so it's time to take the plunge before anybody else picks up that press release. ;)
This may take a couple of hours on the English Wikipedia; the other languages and meta will be done one at a time in sequence and will go much more quickly.
Mailing lists will remain online.
I'll be starting this around midnight PST (8am UTC, 9am CET).
