I received a string of unrecognizeable errors with the Directions API early this morning start from August 28, at 3:49 AM EDT and ending around 5:00 AM EDT.
At 3:49 AM it started with a web exception attempting to send a request to the Directions API:
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 22.214.171.124:80
At 3:51 AM we recived another error while attempting to send a web request
System.Net.WebException: The request was aborted: The operation has timed out.
At 4:06 AM and stretching all the way to 5:00 AM we received two errors when sending web requests
System.Net.WebException: The remote server returned an error: (504) Gateway Timeout.
System.Exception: Map quest directions calculation failed. Error processing request: Error invoking doRoute: Error invoking doRoute: route.tt.b2b.mapquest.com
The last exception message in bold is one I have never seen before. That error came from a succesful request to Directions API and is contained in the response of that request.
What are the causes of these errors during that time period?
