Update: Apple says all services are restored.

Following an outage of many Apple services earlier this week, several of Apple’s iTunes and App Store services are again today experiencing disruptions, according to Apple’s system status page.

Apple is currently listing outages for the App Store, Apple TV, iBooks Store, iTunes in the Cloud, iTunes Match, iTunes Radio, iTunes Store, iTunes U, Mac App Store, and OS X Software Update.

The company says that only some users are affected and currently “unable to access multiple services and stores or make purchases.”

Following the outage earlier this week, which also hit some of Apple’s own stores, Apple blamed the outage on “an internal DNS error at Apple,” and apologized to customers for the inconvenience.
