Apple has reported some brief but widespread slowdowns and unavailability of Game Center -- starting in the wee hours of Thursday and again later that morning -- coupled with a prolonged mail issue that only affected a fraction of one percent of users on iCloud.com for half a day over Thursday and Friday. The disruption comes on the heels of scattered reports of brief iTunes Store outages and a more serious iMessage and FaceTime problem ten days ago, the latter of which lasted over five hours. All services are back to normal operation now.
