Somehow the list of repos under "Everything" does not list any extension any more, and does not find much any more because of this. We learned to rely on this quite heavily. I'm afraid this will make people think code is unused, when it is.

Fixed by just restarting the hound process. I'm not exactly sure why they disappeared, my best guess is that for some reason ExtensionDistributor returned an empy list of extensions (e.g. because Gerrit was down), then codesearch copied that and suddenly had no extensions.
