Yup. I cache with my phone, and I was in the middle of logging a find and got a strange message. (Data downloading, please try another time. Or something like that.)
Then I couldn't pull up any details for any other caches or log any other finds. Tried 3 different apps: new app, old "classic", and c:geo. All just gave me the spinning wheel like it was trying to load. Tried going through my browser, an that didn't work either. That was at appox 6 PM Central.
After giving up and doing some errands, I tried again, and still nothing. (7:30 PM Central).
Now on my computer, and still can't pull up cache descriptions or log finds. But one log that I saved while in the field went through on the c:geo app. But now it's all down again.
