Apple has apologised for yesterday’s outage that saw customers unable to access a host of the company’s online services.
The 11-hour blackout meant that users couldn’t make purchases through iTunes, the App Store, the iBooks Store, and the Mac App Store.
What’s more, the issue affected users globally, maximising the damage to one of Apple’s core revenue streams.
“We apologise to our customers experiencing problems with iTunes and other services this morning,” said Apple, speaking in a statement.
It added: “The cause was an internal DNS error at Apple.”
DNS stands for Domain Name System. That’s the system that takes a URL like www.trustedreviews.com, and then converts it into an IP address that directs to a website’s server.

According to calculations by IBTimes UK, Apple missed out on a staggering £17.6m in revenue as a result of the failure.
That’s based on first-quarter financial results from Apple that revealed the company made £3.2bn from ‘Services’.
This was then divided down to discern that the firm makes somewhere in the region of £1.6m every hour from its services.
Fortunately, all services are now back online globally and the purchase inaccessibility issues appear to have subsided.
