Social media services Facebook, WhatsApp and Instagram have been hit by a worldwide outage, international media outlets reported on Monday afternoon.

All three services are owned by Facebook and could not be accessed over the web or smartphone apps.

Downdetector, which tracks outages, logged nearly 80,000 reports for WhatsApp and more than 50,000 for Facebook, the BBC reported.

Messenger was down for nearly 3,000 users.

“Facebook Inc’s (FB.O) suite of apps, including popular photo-sharing platform Instagram and messaging app WhatsApp, were down for tens of thousands of users, according to outage tracking website Downdetector.com., Reuters reported.

Reuters could not immediately confirm the issue affecting the services. However, the error message on Facebook’s webpage suggested a Domain Name System (DNS) error.
