Some users may be experiencing difficulty making purchases on the iTunes Store, according to Apple’s system status page. We’ve heard mentions of issues beginning this morning, and Apple reports trouble starting around 1:30 PM EST. Game Center and FaceTime also experienced issues this afternoon, though the former may be somewhat difficult to notice.

Apple’s iMessage service has been suffering turbulence for days now, which is not reflected on the system status page as it may be limited to iOS 7 users. Apple told the WSJ it is working on a fix for its iMessage issues in a future software update and recommends a workaround in the meantime.

Update: Apple says the 90-minute outage has been resolved, but expanded the list of affected services after the resolution: “Users may have been unable to make purchases from the App Store, iTunes Store, Mac App Store, or iBookstore. Users may also have been unable to access iTunes in the Cloud, iTunes Match, or restore purchases from an iCloud backup.” Let us know if you see anything else!
