San Jose statistics for the cluster and it's the Wikia engineer's playgrounds for testing. You can generally see the changes made in TRAC are done immediately to the engineer's Devbox. Of course, that only happens if the feature is enabled on that particular Devbox. You'll be more likely to see the feature enabled on the creators of the extension as listed in the extensionName.setup.php  line.
