In my profile and in all that access the warnings: "There was a problem loading ... top artists, please try again later." "There was a problem loading ... top albums, please try again later." "There was a problem loading ... top tracks, please try again later." They are shown
Very sorry about this - something broke at approximately 1am this morning, and unfortunately this specific problem didn't correctly trigger our internal alert monitoring system which would have woken up our engineers. So it wasn't discovered until they came in to work this morning. In addition to fixing the problem, we're setting up better alerting for problems with user libraries so that our engineers can respond more quickly, should this issue happen again.
Thanks for your patience and, once again, sorry for the disruption caused last night.
