All outages are focused in major US cities, including New York City, Los Angeles, California, and Dallas, Texas, with problems also occurring in the United Kingdom and portions of Europe.

Reports for each of the cellular networks began to appear within minutes after all of Facebook’s applications broke, according to Down Detector, an internet site that tracks outages.

The news of the outage comes after social media platforms Facebook, Instagram and WhatsApp, along with Amazon Web Services, have also suffered a similar fate earlier in the day.

Users all over the globe experienced outages as the applications stopped working on both the web and smartphones. This happened with Android, iOS and web platforms.

For Facebook users, they were redirected to an error page with a message reading on the screen, saying that their browser could be connected.  

As per reports, DownDetector reported a quick spike in the number of cases of WhatsApp not working for users on October 4. The same issue was observed with Instagram, as well. The outage happened at roughly 9.15 pm IST.

Some speculate that the outages are connected, but none of the companies has confirmed.
