When you’re a service that used by more than a billion people across the globe, it’s hard for an outage to go unnoticed because people instantly start asking questions on social media about what’s wrong. That’s what happened on New Year’s Eve when WhatsApp went down in several markets across the globe. Fortunately, it didn’t last long and the Facebook-owned service was able to get things up and running again.

Reports about WhatsApp going down came in from all across the globe. The largest concentration of outages were reported from parts of England, Germany, Italy, Spain, Central Europe, and almost all of the Netherlands. Reports also came in from parts of Asia and South America.

Reports also came in from major cities like Dubai, Rio de Janeiro, Toronto, and Kuala Lumpur. It wasn’t immediately clear what caused the outage on one of the busiest nights of the year, one where people rely on these services more than ever to stay in touch with friends and family.

Reports about the outage surged around 9 am Pacific while a spokesperson for WhatsApp has said that the outages started around 10:30 am Pacific. “WhatsApp users around the world experienced a brief outage today that has now been resolved. We apologize for the inconvenience,” the spokesperson said. No explanation has been given for the outages.
