The services have now been down for approximately seven hours and the long outage may have cost Apple millions of dollars in lost sales.
Although this morning, the page claimed that all services were functioning well -
despite there being problems but it has now been updated to show that the App Store, iTunes Store, Mac App Store and iBooks Store are all 'unavailable to all users'.
Currently music, film and TV content is visible in the iTunes Stores, but users can’t buy it.
Some users have seen error messages, while others are simply unable to download the goods they want in the digital stores.
The front pages of both the App Store and Mac App Store are accessible, but there are broken pages on the sites when accessing individual apps.Currently some customers simply see a spinning circle indicating that a song is in the process of being downloaded, but nothing happens.
Others are shown an error page saying that content cannot be displayed, or that the store is temporarily unavailable and could not complete their request, when they try to download an album.
The status page also reveals that some users had problems accessing their iCloud mail this morning and may have been unable to sign in.
A post from Californian tech giant's Apple Support twitter handle said: 'APP STORE ISSUE: You may be receiving an error this morning. Apple are currently working on this and we do apologise.'
In 2014 Apple revealed in that it had made $18.06 billion in revenue from iTunes, including its software and services, making up 10 per cent of Apple's total net sales.
