The websites and apps for all of the services were responding with server errors. Reports on DownDetector.com showed the outages appear to be widespread, but it’s unclear if it impacts all users or just some locations. It’s not currently known what’s causing the outage.
All three platforms stopped working shortly before noon ET.
In 2019, a similar outage lasted about an hour. Facebook said that outage was caused by a technical issue. Major websites can also sometimes go down if content delivery networks, or CDNs, go offline. That happened in June, when one such CDN, Fastly, was down due to technical issues. That caused major websites including Amazon, Reddit and The New York Times to go down.
