The ‘system status’ page was updated by Apple around 7:30 PM Pacific, reflecting restricted availability for various services including App Store, iTunes Match, iTunes Store, Apple TV, iBooks Store, iTunes Store and Mac App Store.
This downtime of the store services affected users who were unable to have complete access or use the Apple website, along with others such as Apple Online Store, Apple ID, Apple Music, FaceTime, iCloud, TestFlight, iMessage and several other services, eventually hinting that Apple had Server or DNS issues.
The severity of the downtime was seen when Maps service was unavailable around 7:50 PM and lasted about half an hour until the issue was fixed. Apple Maps servers indicated users who were trying to use Maps during that period experienced problems due to the unavailability of the service.
There’s no clear explanation for the downtime though, the system status page said the were evaluating the reason behind the downtime and will update as more information becomes available.
By 8:45 PM, there was an update on the system status page, indicating the issues were fixed and the services had resumed functioning once again.
