Don't know why it says "FIXED" in the previous post. It's only fixed if you have an Intel machine, upgrade to Snow Leopard or higher and hack around in the system files.
Don't get me wrong... I'm messing around in the system all the time and use the Terminal frequently. But I don't have an Intel machine.
If someone knows how to correct this for Tiger users, it would be appreciated.
However, while playing around with this I found out several things. The AccuWeather widget also used the "panther" addresses mentioned a couple posts up. Apparently those URLs were used by AccuWeather's servers for some reason (why there were nearly 100 different URLs that varied only by 2 or 3 numbers, boggles my mind). However as of this afternoon (11/15/2011) the addresses AccuWeather and the Apple Weather widgets used, suddenly changed, and they have now returned to the wu.apple and apple.accuweather addresses.
The problem, the standard weather widget still fails to receive weather data and stays blank with just the degree symbol in the corner, and several dashes for temperatures. The AccuWeather widget does work (though it went to an edgesuite address once already for some reason). I hate the thing as it is very hard to read and harder to figure out what the abstract symbols are at the size they are with the backgrounds they are on.
Why they are playing games with the addresses, I don't know. And the several hundred other addresses the standard Weather widget was going to (the ones at the questionable locations), still hasn't been explained.
Again, can someone please help us find a correction for non-intel machines, or at least let us know if Apple will correct this where the problem lies... at the server end?
