|Apple's iTunes Match storage and streaming service is currently down for at least some users, says AppleInsider. Trying to play content hosted on Match only results in tracks sticking at the "0:00" mark. The trouble notably follows outages of iMessage and FaceTime, which hit users of Macs and iOS devices on Sunday.
Those services were down for several hours, but were restored by 4:41PM Pacific time. Apple has had several iMessage outages in the last three months, including one in September and two in October. iCloud, the backbone of Apple's Internet services, has in fact been experiencing periodic interruptions since it was switched on last year; problems with Mail, Contacts, and Calendars have been more common than issues with iMessage or FaceTime, however.
