I’ve just used the Control Panel to report an outage at the DreamHost Wiki - some sort of database error I think. It may take a while to get sorted out because there are a large number of outstanding support requests. For what it’s worth, I also moaned about the need to upgrade it to a more recent version of MediaWiki, but I’m sure that’ll fall on deaf ears as usual.
Looks fixed now. (Support queue is still a bit long tonight)
