Good question for the geocaching.com forum. The Mapquest maps are the old way. The maps you refer to are the "new" Google maps. For some reason, we're back to the old maps.
Thank you!! I thought I was losing my mind! I hope it goes back, I really liked the Google map. I noticed I can click on the google map on a cache page, but it will only let me see that one cache, not a bunch like the other map did. But, Thank you for confirming that i'm not (completely) crazy!!
