WASHINGTON (TNND) — Billionaire and Tesla CEO Elon Musk is blaming a "massive cyberattack" for the waves of outages impacting X on Monday.

The problems began around 6 a.m. ET, according to the outage tracking site DownDetector, and temporarily went away before another outage was reported by 40,000 users at 10 a.m.

As of 2:30 p.m., the outages had not been resolved and no details were provided about what may be causing the issues.

Musk wrote on X that he believes a "large, coordinated group and/or country is involved" in the "massive cyberattack."

The last big issue impacting X happened in August 2024 when the social media platform faced technical difficulties during a stream with President Donald Trump.

Musk claimed the issues were caused by a "massive DDOS attack."

"There appears to be a massive DDOS attack on X. Working on shutting it down," he wrote, referencing a "Distributed Denial of Service," which is a federal criminal act that involves flooding a site with data to overwhelm it and knock it offline.

The platform, originally Twitter, was purchased by Musk in 2022 for $44 billion and officially renamed X in May 2024.
