Apple apologized to users after a major outage of its online services, affecting customers worldwide.
The tech giant’s status page showed the App Store, iTunes, iBooks store and Mac App store went down from 0900 GMT and were still offline at 1900 GMT.
Similar outages were seen in Apple online services in Britain and France. The Next Web, the international technology news site, said it had reports of outages affecting more than 40 countries.
“We apologize to our customers experiencing problems with iTunes and other services this morning,” Apple said in a statement emailed to AFP, blaming an “internal” domain name system error.
“We’re working to make all of the services available to customers as soon as possible, and we thank everyone for their patience.”
Apple’s iCloud and mail services were also down, but appeared to have been restored after around four hours, according to the status page.
Other services such as FaceTime, messaging and Apple TV did not appear to be affected.
The outage made it impossible for iPhone and iPad users to download music or to install or update apps on their devices.
Apple support forums included complaints from users around the world, including the Netherlands and Iceland, unable to install or update apps.
Reddit forums mentioned problems from users in Britain, Australia and elsewhere.
The news comes two days after Apple announced details about its smartwatch, which will be available in several markets on April 24, along with a new Macbook computer.
Apple said at the event that it has sold more than 700 million iPhones since launching the device in 2007.
