I am a software engineer at Asher Group. We use the mapquest geocoding webservice api quite a lot. We queried the api on Sep 21 at 04:05:57 for address 3300 Monroe Ave, 14618. But the response from the api was incorrect, it gave us the coordinates 39.78373, -100.445882 (which is in Kansas I think ) whereas it usually gives 43.103379, -77.53878 ( which is in Rochester, New York ).
Getting an incorrect response of that magnitude can result in bad things for our application.
I hope you look into it and get back to me.
Thanks and have a great day.
