Apple's iCloud is back online after complained of brief outages Friday afternoon, technology blog 9to5Mac reported.
There was "connection error" when users tried to log on to the service, which backs up Apple mobile devices to the cloud and powers messages and emails, according to tweets to Apple's official support Twitter.
Apple's status page, which tracks system issues, showed a brief iCloud outage around 3 p.m. Eastern Time, and a third party system called Down Detector also showed a spike in complaints. Apple did not specify what caused the issue but told CNBC it had been resolved.
App developers have also started to warn users of the issues, 9to5Mac reported.
