Temporarily unavailable: One or more weather radar stations are undergoing repairs or maintenance. We have to wait for the local weather service to finish their work.
Permanently unavailable: In general, if a region is not supported then this is because the data is too expensive, the weather service is not responsive to our requests, they are too bureaucratic, or there are no weather radar stations.
