HRD issue at the moment? Server Error (500) from GAE Admin Panel

[Marcel Manz]

My application currently is unable to access certain entities, nor is the datastore viewer. When I access a certain kind it immediately displays a Server Error (500) in the GAE admin panel:

Server Error

A server error has occurred.

Return to Applications screen »

Further I notice that in 'Datastore Statistics' there currently are no kinds selectable and only 'All Entities' are shown in the drop down selector. So does 'Datastore Admin' report 'Stats not available' in every column.

Some issues going on?

@Google: You can PM me for app id and kinds that are causing problems.

Thanks
Marcel
