After an outage of nearly four hours for some users Thursday, Google said its popular Calendar app is back up and running fully.
Google initially reported on its Apps Status Dashboard that Calendar was down at 9:47 a.m. ET.
Users from around the U.S. reported receiving a “Server Error” message when they tried to access their Calendar app. It's not yet clear how many countries were affected.
At 11:33 a.m., the company reported, "Google Calendar service has already been restored for some users, and we expect a resolution for all users in the near future."
At 2:36 p.m., Google reported on its Dashboard that the problem had been fully resolved.
“We apologize for the inconvenience and thank you for your patience and continued support,” the company said. “Please rest assured that system reliability is a top priority at Google, and we are making continuous improvements to make our systems better.”
The cause for the problem wasn't reported.
During the outage, the problem also seemed to affect Hangouts. Various reports surfaced from users who said they were unable to connect to a Hangout through Calendar.
As usual, people took to Twitter to vent their frustrations, and have a bit of a laugh, at Google's Calendar problems.
"Google calendar is down and i hope they do a post mortem and explain what happened and then i realized THEY CAN'T EVEN SCHEDULE THE MEETING," tweeted @ftrain.
And @rkiker tweeted, "Google Calendar is down. Where am I?"
