It seems the option to view the seat map has disappeared from the Flight Status web pages? Anyone else noticed this? It was there yesterday morning, but had disappeared by some time yesterday afternoon. If I go to view random flights today I can't see it on any of them. Deliberate or glitch?

This will be a huge inconvenience if deliberate, I use that feature all the time, it's really one of the things that distinguishes United's online service from other airlines, why would they get rid of it?
