With a lot of experimental code that doesn't get looked over as closely or as quickly as we might all like, I'm not willing to run a CVS HEAD-based test.wikipedia.org on our main servers anymore. I've discovered too many holes in code weeks after it went up on test to be comfortable leaving unvetted code running on our production servers.
At some point we may set up a separate test wiki on one of the non-main-cluster "test" boxes.
