Users may be experiencing difficulties accessing ProtonMail. Tuesday 12th October 2021 17:45:00


Users may be experiencing difficulties accessing ProtonMail. Our team is investigating this, and are working to bring our services back online ASAP. We’ll share updates on http://protonstatus.com as soon as we have more information. We apologize for the disruption.

The downtime was caused by an application deployment that triggered a high load on our servers. The standard recovery procedure wasn't enough to successfully restore the services, so we had to perform a few extra actions to restore the web servers. As a result, services were down for about 30 minutes for some users; no emails were lost. We are taking steps internally to prevent this issue from reoccurring. Once again, we really apologize for the inconvenience.

A while ago, we finished restoring services. We confirm no emails lost, but some may be delayed. Services were down for about 30 minutes for some, but not all users. We apologize deeply for this unexpected downtime and will share technical details later after we finish our analysis.
