If the main API website is down, you can use this backup server. Simply replace connect.carsimulcast.com with connect.carsimulcast.co (the only difference is the "m") in your API URLs to continue using the backup server with your existing API credentials.

Please note that backup servers may also go down from time to time. They are provided as a precautionary measure, and you should always use the main API whenever it is available. All account credits and history are synchronized between the main and backup servers, so no data will be lost.
