I had changed it a couple of weeks back to point to our COB region, which is up only during a specified time, and didn't realize I hadn't changed it back. But I also thought that stopping and starting the app in the manager console would overwrite the app xml file in the conf folder, and that didn't happen. I checked it there and discovered the problem. Thanks, though.
