Weather service not working anymore?

[jetsetter]

Hi, for quite some time, I am using the http://openrb.com/weather/?w=citycode to get weather data for my city code in a script every minute, but since this morning, the service returns error status:
{"error":true,"cause":"load failed"}

I have used also different city codes, but I get the same error. Is there a temporary problem or we cannot use this service anymore?
