Messaging platform WhatsApp had begun to return online by 2:00pm and the company said the issue has been fixed after users across the world reported problems earlier on Tuesday.
A report by outage tracker Downdetector showed the app went down shortly before noon, with #WhatsApp the top trend on Twitter in Pakistan with more than 85,000 users talking about the outage.
Users reported being unable to send messages, with the app showing “connecting”. However, by 2pm some users reported being able to send and receive messages.
