  4. resolved Oct 30, 2025, 10:07 AM UTC

    All services are back online. Earlier today a small portion of our userbase had issues accessing some of our products. The disruption was caused by a partial power failure in Proton's Oslo datacenter which caused our system to be unable to tell if the datacenter was online or offline, requiring us to manually divert impacted traffic to other locations. The impact has since been mitigated, no user data was impacted, no email were lost and delivery is resuming.
