WhatsApp is down for millions of users around the world, causing panic for New Year’s revellers trying to make plans and wish their friends a prosperous 2018.

Users across the UK and in countries including Barbados, India, Japan, Panama, South Africa, Spain, and Qatar said they were unable to connect to the app.

It is unclear if the service suffered outage in other parts of the world as well. People have taken to Twitter to complain about problems with the messaging service. The outage this time round has been pretty long, response from users suggest it’s more more than an hour.

Users from different countries are reporting problems on Twitter with the hashtag #whatsappdown. We’re facing problems in India as well, with no messages going through, and navigating to the Help > Contact Us section shows this error message:

This comes at a particularly bad time for party goers as people begin their New Year celebrations. Some were speculating that it could be due to the sheer number of people trying to send messages to loved ones.

But the situation will prove more permanent if you’re using the Blackberry OS and BlackBerry 10 operating systems, and Windows Phone 8.0 and older.

Support for the Nokia S40 will also stop after tonight, while Android versions 2.3.7 and older will cease to function from February 1, 2020.
