Facebook said it was "back at 100 per cent" Wednesday evening after an outage on all of its services affected users in various parts of the world.
Online monitoring service DownDetector reported earlier the outage began around 1200 GMT and affected Facebook as well as its Instagram and WhatsApp services.
"The issue has since been resolved and we should be back at 100% for everyone," the company tweeted at 0006 GMT Thursday, adding they were sorry for "any inconvenience."
"No, we didn't cause it. No, we can't fix yours. Did you try turning it off and back on again?" Earlier this year, an outage lasting as long as 24 hours that hit Facebook services was blamed on a "server configuration change."
