Now that Nagios doesn't suck, we can actually see the scripts outage caused by the AFS server restart every Sunday morning. This made me realize a few things:

• Our fallback to hodge-podge isn't just an exceptional condition; it happens every week. Thus it's an even worse idea than I thought it was. Viewers will get confused, and search engines may remove pages from their indexes, if they happen to get a 404 error from hodge-podge at the wrong moment.

• Since the heartbeat script is in the scripts locker, the AFS server that serves it (aegisthus) is a single point of failure. Ideally LVS would check multiple heartbeat scripts in lockers on several different AFS servers, and continue routing connections if any of them respond.
