There was a partial downtime earlier today, impacting different services at different times over a roughly half-hour period. Services have been fully back online since approximately 17:40 Zurich. Due to redundant systems, no data was lost, but some emails may be delayed. If, for some reason, you continue to have temporary issues connecting to Proton services, please try using a different device, different internet connection, or VPN server. Proton's 24/7 infrastructure and security teams are continuing to monitor the changes we have implemented to strengthen our infrastructure today. We are leaving this incident open for the time being as we may add more technical details later.
