Elon Musk claims X crashed because of a massive cyberattack

Elon Musk claimed Monday that X suffered a “massive cyberattack,” which caused the site and app to crash throughout the day.

Musk quoted a post theorizing there was an attack on X, claiming that was, in fact, the case.

He wrote: “There was (still is) a massive cyberattack against 𝕏. We get attacked every day, but this was done with a lot of resources. Either a large, coordinated group and/or a country is involved. Tracing …”

Musk didn’t provide evidence that X was under attack and isn’t always the most reliable source of information. He previously claimed a Spaces interview with then-candidate Donald Trump suffered an attack in August of 2024, for instance, which X employees said wasn’t true.

Whatever the case may be, X first crashed for many users in the early hours of Monday morning, Eastern time. According to user reports on Down Detector, it seemed to rebound and re-crash a few times throughout the day. Things appeared to be mostly fixed by Monday afternoon, Eastern time.

Musk himself was back to posting conspiracy-adjacent attacks at his perceived enemies. So things were back to normal.
