Update 2 9:45PM ET: Users this evening again reported issues centered around iCloud. The outage affected all store services, according to Apple’s status page. It appears to have been resolved, however, with the exception of Game Center.
Update: After about an hour of downtime and still with no admission from Apple of anything ever having gone wrong, iCloud services seem to be coming back online now.
Despite being listed as fully functional on Apple’s status page, it seems iCloud is once again down for many users. Reports across Twitter and in our own experience here at 9to5Mac have verified that iCloud and the App Store (and possibly other Apple services) are currently down.
