WhatsApp was inaccessible for about two hours in several countries worldwide Tuesday, leaving Meta engineers scrambling to identify and resolve the issue in the early morning hours.

WhatsApp started to return to return to operation at around 2.10 a.m Pacific Time, providing relief to billions of users and businesses that rely on the Meta-owned instant messaging and calling app.

WhatsApp didn’t share what caused the outage, but confirmed it has fixed the issue. “We know people had trouble sending messages on WhatsApp today. We’ve fixed the issue and apologize for any inconvenience,” a Meta spokesperson said.

Earlier in the day, users across the globe started to complain that they were unable to send or receive new messages, sign up for WhatsApp, update their profile information or privacy settings, they said.

DownDetector, a web service that tracks services performance, said tens of thousands of people complained about the outage when WhatsApp was down. WaBetaInfo, another popular service that tracks WhatsApp, reported that the issue was “server-side,” meaning users couldn’t do anything to resolve the issue.

In an earlier statement to TechCrunch, a Meta spokesperson said the company was working to restore WhatsApp for “everyone as quickly as possible.”

Users are seeing several errors accessing WhatsApp, including the app’s inability to connect to the server.

Jagmeet Singh contributed to the report.
