Popular messaging app WhatsApp has gone down in a number of locations around the world and people are not happy.

WhatsApp users in Mexico, Spain, Chile, Israel, Russia, Ireland, Switzerland, Aruba, Turkey, the US, Ghana, Nigeria  and other locations have experienced problems, according to social media reports.

According to DownDetector.com, which provides a realtime overview of issues and outages online, WhatsApp has been experiencing issues since 8pm GMT, with users reporting problems with the app’s connections, sending and receiving messages.

The Facebook-owned messaging service, which has more than 1.2 billion users worldwide, has yet to release a statement on the outage.

WhatsApp’s last major outage happened on New Year’s Eve, when the service was knocked offline for a brief period in a number of locations around the globe.

A WhatApp spokesperson said at the time:“Some people have had trouble accessing WhatsApp for a short period today. We’re working to restore service back to 100 percent for everyone and we apologize for the inconvenience.”

Here are some of the possible reasons for the whatsapp offline issue:
