Sounsd like London's Underground system is almost as bad as Sydney's train system. They seem to provide more information about it though..

Via BoingBoing:

Cory Doctorow: Stef sez, "For 15 days, I've been grabbing the London Underground realtime disruption map every few minutes. I've just glued them all together into a three minute Quicktime, so you can visualise just how bad London's subway system is. My calculations indicate that the system is only fully operation 22% of the time!" Link (Thanks, Stef!)
