Is Proton Mail down?

Some Proton VPN servers are currently unavailable. We are working with the upstream datacenter in order to solve the issue as soon as possible. We apologize for the inconvenience.

This incident has been resolved.

Some users on MacOS may be seeing errors stating that our Proton Mail & Proton Meet apps are qualified as malware. This is an error, there is no actual malware threat, and we're working together with Apple to restore functionality for our MacOS users. For context, earlier today one of our developer accounts with Apple was revoked for unknown reasons, causing previously legitimate apps to be blocked at the operating system level on MacOS. In the meantime, we recommend using the webapps. Apologies for the disruptions caused by this, we will communicate further once we have more information and updates.

Dear Proton community, On Friday, October 2, 2026, an issue with Apple's developer program caused Proton Mail for Mac and Proton Meet for Mac to stop opening on macOS for some users. MacOS also incorrectly flagged them as malware in some cases. Your data and accounts are safe. The apps were not compromised, and the malware warning was a false positive. While we continue to work with Apple to resolve the situation, we have also released new versions of the apps to work around the problem for affected users. If you find that either Proton Mail for Mac or Proton Meet for Mac fail to open, you may need to download and install the app again from the links below. We apologize for the inconvenience. - Download Proton Mail for macOS from https://proton.me/mail/download - Download Proton Meet for macOS from https://proton.me/meet/download Stay secure, The Proton Team

We've now updated both the Proton Meet and Proton Mail MacOS desktop apps. If you're still receiving a pop-up on your device, please update to the latest version of the desktop apps. Once again, we apologize for any inconvenience this has caused.

We’re aware that a small number of users may be experiencing issues accessing Proton services. Our team is investigating and we will share updates here as soon as possible. We apologize for the inconvenience.

We are continuing to investigate this issue.

Database capacity is being restored. Traffic limitations are being gradually lifted and outgoing mail will be re-enabled as soon as the situation is stable. Queued emails will be delivered progressively, and no data was lost as a result of this disruption. Thank you for your patience, we'll update you again once everything is back to normal.

Traffic limitations have been fully removed for all users. Services are returning to normal operation, and outgoing mail will be gradually re-enabled in 15 minutes. Messages that were queued during the disruption are being delivered progressively Our engineers continue to monitor the infrastructure closely as capacity returns to full levels. We'll confirm here once everything is completely back to normal.

This incident has been resolved.

We have identified a critical cooling failure in our Frankfurt datacenter. We are currently in the process of shifting traffic to our backups sites.

Our efforts to restore impacted services are now yielding results, and as a result are starting to recover for some users. Meanwhile, we are continuing recovery operations.

A fix has now been implemented, and we're monitoring results. This means most services have been recovered for most users now, but our efforts to recover the remaining instances continue.

This outage has now been largely resolved, and services are back online. We are still clearing a few lingering issues, however, meaning some users will experience delays in email delivery and reception, and receiving notifications. No data has been lost as a result of this outage.
