The messaging app was down on Tuesday morning. WhatsApp said it was working to restore service as quickly as possible

“We’re aware that some people are currently having trouble sending messages and we’re working to restore WhatsApp for everyone as quickly as possible,” Josh Breckman,

a WhatsApp spokesman, said in a statement, which did not specify the extent of the problem.

Internet service outages are often restored within a few minutes or hours, but given WhatsApp’s size and position as an indispensable communication tool in many countries

every second without access has added consequences. People immediately took to Twitter to raise questions about the outage

writing in German, Hindi, Indonesian, Portuguese, Spanish and other languages.

WhatsApp, which is owned by Meta, the parent company of Facebook, lets users make calls and send text messages for free over the internet

and is particularly popular in Africa, Europe, India and South America. It has more than two billion users around the world, the spokesman said.
