If you're unable to update your apps or buy books and music on Apple's content stores, you're not alone — there's trouble in iCloud. Apple's App Store, Mac App Store, iTunes Store and iBooks Store services have been experiencing widespread outage for straight six hours now.
At first, the company's iCloud Status Page would not acknowledge the downtime. Earlier this morning, the company refreshed the dashboard which now shows the App Store, Mac App Store, iTunes Store and iBooks Store as being unavailable “for all users”.
UPDATE: following what became an eleven-hour long outage, the App Store and iTunes services are now back online.
