The Google Calendar is back up after it crashed for many users all over the world Thursday, inconveniencing a large number of people who depend on the application for access to their daily schedule, personally and professionally.

The service interruption meant that some Google Calendar users were unable to access the service they use to store information about where they should be and what they should be doing at every hour of the day. Many users likened the event to the end of the world.

Alphabet Inc.’s Google said the outage affected consumer and corporate accounts that pay for its services, showing a page titled “server error” when users tried to access their calendars. The company said service was restored for some customers around 11:30 a.m. EDT and that it expected a full resolution “in the near future.”

Even though the extent of the disruption wasn’t clear, a fraction of Google users would also account to millions of people. Google’s email service, often used in conjunction with calendar, has more than a billion users, reported the Wall Street Journal.

Other than regular consumers, Google’s business customers, who use Google service to run their companies and manage employee schedules, were also affected adversely.

Users took to social media to voice their displeasure.
