X was down for more than two hours, with thousands of users affected.
“Make our message reach to Elon Musk: ‘Open Starlink in Sudan’,” the hackers posted on Telegram.
The website outage-tracking site Down Detector said nearly 20,000 outage reports were logged by users in the US and the UK.
X did not publicly acknowledge the disruption caused and Musk did not comment either.
The cyber-attack flooded X’s servers with huge amounts of traffic to take it offline.
