On Monday morning, Elon Musk’s social media platform, X—formerly Twitter—suffered substantial outages that disrupted the experience of thousands of users in both the United States and the United Kingdom. Reports from the outage-monitoring service Downdetector indicated that tens of thousands of US users experienced technical difficulties, with over 8,000 reports emerging from the UK just before 14:00 GMT, following a notable surge in complaints throughout the morning.

Users attempting to engage with the platform during these outages encountered persistent loading icons on both the mobile application and desktop interface. In an unusual assertion, Musk attributed the disruptions to a “massive cyber-attack” purportedly originating from the Ukrainian region. However, despite his claims, he provided no substantive evidence to corroborate this theory and refrained from suggesting whether state actors might be implicated. Earlier, he indicated on X that the incident possibly involved “either a large, coordinated group or a nation-state.”

Alp Toker, director of Netblocks—a digital infrastructure monitoring organization—argued that the nature of the outages aligns with past denial-of-service attacks, rather than stemming from configuration errors. He noted that the occurrences presented in excess of six hours of significant downtime, a troubling pattern indicative of an extensive assault on X’s infrastructure.

As a further complication, Musk vocally criticized US Senator Mark Kelly, labeling him a “traitor” for his recent visit to Ukraine, where Kelly emphasized the imperative of supporting the Ukrainian populace. In response, Kelly countered Musk’s remarks, advocating for the essential values underpinning American freedom.
