Who is the new map provider that is being tested?

This new map service does not work for our company at all. We use the quick google box for roof shading analysis (we are a solar company). The satellite view for new mapbox is not as good as google. Now we have to take an extra step and click on the link to use google map. 

I will have to figure out how to input a customer google box since nobody in my company likes the new mapbox.... :(
