This is a non-technical question, but certainly relevant for the TCS community. If considered inappropriate, feel free to close.
The Complexity Zoo webpage (http://qwiki.stanford.edu/index.php/Complexity_Zoo) has certainly been of great service to the TCS community over the years. Apparently it is down since quite a while. I was wondering, if someone is still maintaining it, if it has moved, if there is a backup server, or if there are other plans to preserve this wonderful database of complexity classes, their relationships and citations to relevant publications. If not, are there comparable webpages that could be used as a replacement?
UPDATE (Aug 1): The Zoo is back online, and Scott is looking for people volunteering to mirror it to avoid any future outages.
