I'm not sure if this has been stated yet but it is confirmed by many people and still resides on Test.

The area change from Rome Green (Southeast) to Rome Red (Southwest) receives "unable to change area" messages after timing out for an extended period and then you get a quick load again and zone over. This has been like this for months so if you could take a look at that and fix it, I would be very appreciative as many of us spend a lot of time in Rome (due to the nice scenery).

It doesn't happen 100% but does happen about 75% of the time.
