Proton Outage: Conflicting Reports on Cause Between Cyberattack Claim and Cooling Failure

A global Proton AG outage on August 27, 2026, has prompted conflicting explanations. A pro-Iran hacktivist group, Islamic Cyber Resistance in Iraq – 313 Team, claimed responsibility for a cyberattack, while Proton AG attributed the disruption to a critical cooling failure in its Frankfurt datacenter, not acknowledging an attack. The discrepancy raises questions about the incident's true nature and potential security implications.
