Tech billionaire Elon Musk has claimed that his social media platform, X, was targeted by a “massive cyberattack,” with indications that the attack originated from Ukraine.

On Monday, X experienced multiple outages, going offline repeatedly before briefly recovering and crashing again. Users reported difficulties loading posts and accessing in-app services.

Speaking to Fox Business Channel, Musk stated, “We’re not sure exactly what happened, but there was a massive cyberattack to try to bring down the X system, with IP addresses originating in the Ukraine area.” When asked about the platform’s status, he simply responded, “It’s up.”

Earlier in the day, Musk confirmed that X had been hit by a large-scale attack, which led to service disruptions for thousands of users. “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…” he posted on X.

Musk’s comments followed speculation from his supporters that the attack was part of broader targeting against him, particularly after reports of vandalism at Tesla stores across the U.S. The backlash is believed to be linked to his role in the Trump administration’s Department of Government Efficiency (DOGE), which aims to streamline federal operations and cut government spending.

Reports of X outages spiked early Monday, with disruptions peaking at around 3:30 a.m. and 10 a.m., affecting over 40,000 users. According to DownDetector, a platform that tracks service disruptions, complaints surged again at 3:20 p.m., with over 17,800 users reporting issues. Further outages were reported at 7:32 p.m. and 9:32 p.m.

DownDetector’s data indicated that 56% of affected users faced issues with the app, 33% encountered problems on the website, and 11% experienced server connection errors.
