Facebook’s hours-long outage may have finally ended, and apparently, it’s Apple’s turn for a system outage. The company reported ongoing issues across almost all of its iCloud services beginning at 11AM ET today, which lasted until 3:28pm.

Apple didn’t offer any details about what the issues are, just that “some users are affected,” and “users may be unable to access this service.” But according to the company’s support page, the problem was widespread. iCloud sign in, Backup, Calendar, Contacts, Mail, Keychain, iCloud Drive file storage, iWork, Photos, Notes, Reminders, Find My iPhone, and more were all apparently affected by the issue.

The iCloud outage marks the third major tech outage in as many days, following Gmail and Google Drive issues earlier in the week and yesterday’s widespread Facebook, WhatsApp, and Instagram outages due to a server configuration changes.

Update March 14th, 4:51pm: iCloud is back up and running again as of 3:28pm ET.
