reports

Looks like your stats buckets have been set to be hidden from the public.

Any chance that somebody at your end might have made a change to the ACL list on any of your buckets lately? Maybe you have an automated script running to do this? Looking at the ACL for one of those buckets, it does seem to have quite a complex set of permissions specified, which indicates that somebody has altered it at some point.

Regardless, it seems that your reports are all in place. If you set those report folders to be publicly readable, I expect you'll be able to see your reports.
