It seems that GitHub is doing some maitanance work at the moment. For us it means that UppHub is unavailable. How we should act in such situation? I think we should at least inform users that UppHub is unavailable. Warning prompt should be enough - optimally Oblivion's MessageCtrl should be used Moreover, it would be nice to cache nests.json just in case and display the list anyway. With such approach the nest installation failed if it depends on GitHub, but user will have access to the list.
Here is the screenshots from today's empty UppHub:

If GitHub is down, what is the point of caching nests.json?
