DarkSky upgraded its security protocols

[jasonsalas]

I had some issues connecting to the API through my host, and the developer support team replied with a helpful note:

You can definitively determine whether your app works with the new SSL permissions by testing against https://api.darksky.net:4433/. If you decide to update SSL on your end, you can test the API by sending a request here: https://api.darksky.net:4433/v1/status.txt.

Hope this helps if you're running into a rather non-descript HTTP 500 error. :)
