Isik Mater, the director of research at NetBlocks, a company that tracks global internet connectivity, told NBC News that X had suffered intermittent outages since Monday morning. While establishing a DDoS attack with certainty can be difficult, Mater said, Musk’s claim was plausible.

In a Monday afternoon message on the platform, which according to the site DownDetector has experienced several spikes in outage reports during the day, Musk said, "There was (still is) a massive cyberattack against 𝕏," suggesting that an unspecified country could be behind it.
