I feel like I owe everyone a thank you, and an apology. A thank you because the Carfree webapp started seeing steady use earlier than I expected. This resulted in one of the APIs I was using, specifically one to do an approximate geolocation based on IP address, to reach a request limit. This in turn, caused the Carfree webapp to fail. So, I thank you, and apologize for that.
I’ve switched to a new IP geolocate provider, and the webapp *should* see more stability for a while. At least, where geolocation is concerned.
