Dec 27 drive from Connecticut to NJ to Allentown PA, no routing for the last 3 hours. All requests for routing eventually timeout (some immediately did) reporting it cannot reach routing server.
All other App functions and connectivity-based features are working (alerts, maps, gas prices, hazards, etc)
iOS7 / iPhone 4S
The usual Calculating spinner gives up and error box says:
"Uh-oh:Failed to communicate with routing server"
Strange: it was able to route "back to where I came from" (Massachusetts) but not to points in Virginia or Pennsylvania
