Ubuntu infrastructure has been down for more than a day
Ubuntu and Canonical servers were knocked offline by a sustained, cross-border DDoS attack, disrupting access to critical websites and security communications. The outage coincided with the release of exploit code for a major Linux vulnerability, hampering Ubuntu's ability to issue guidance. While mirror sites continue to provide updates, the attackers—linked to a pro-Iranian group—used a 'stressor' service to carry out the attack.
