@panosrunner I believe the updates indicate the main source for these data feeds is unavailable right now, but there are other ways of accessing the data. Windy may be using the method that is unavailable and are just waiting for it to become available again instead of changing their data source. Other sites may be pulling in the same data from a method that remains available, such as ftp.

Environment Canada provides astronomy forecasts https://weather.gc.ca/astro/index_e.html - I am not sure they do anything more than a North American model, or if anyone else provides anything similar. I use their cloudiness, transparency, and seeing forecast maps all the time through http://www.cleardarksky.com - Clear Dark Sky also models darkness relative to sunset/sunrise and moon brightness.
