So a few days ago, the NA maps were messed up, and people were getting all kinds of crazy routing recommendations from waze. I was one of those affected.

I wrote about it on the forums here when I got home, and the response was that waze had been tweeting about it all day. Sorry, but to me it doesn't seem realistic that all waze users should be expected to monitor waze tweets (or these forums) to know that waze is having a bad day.

Perhaps the developers can implement a "serious system announcements" feature into the waze app. When the waze app is launched on the device, an urgent system status message can be displayed. This would let users know that there are problems, and take appropriate action (such as don't trust waze routing directions today).

These messages would have to be infrequent, and limited to serious issues with the system.
