As you may or may not have noticed, the new version of Drupal (the CMS backend of the site) has some problems. Really, we would've just left the old version, but there was a serious security weakness.

At any rate, the complaint is usually the layout missing some crucial elements (like the login box, or the "maps" entry in the content type list) - just refresh your browser and the problems seem to go away.

If there are any unsolvable problems, use the "contact admins" or comment on this thread and we'll try to work it out.

We apologise for the inconvenience.

Edit: on further inspection, it may have to do with the "throttle" system. Likely the new version improved "throttle"'s sensitivity. This module converts the site into a lower-bandwidth form when the load is heavy. While I'm not positive that this is the source of the problem, it means that said features are disabled when too many users are hitting the site. Dunno how to tweak it to work better. More as it develops.
