Is Proton Services Down?

This incident has been resolved. --- [2026-10-27T16:22:47.976+01:00] (investigating) 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.

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. --- [2026-10-02T18:51:46.445+02:00] (investigating) 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 --- [2026-10-02T16:54:09.018+02:00] (investigating) 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.

UPDATE: The incident recovery caused some push notifications related to suspicious login activity to be delivered several hours later than expected. The delay affected only the delivery of these notifications and was related to the service disruption experienced earlier today. The delayed notifications have now been processed, and the system has returned to normal operation. We apologize for any confusion this may have caused. --- Earlier today, a subset of Proton users experienced intermittent service disruptions. The incident began during exceptional database maintenance following last week's datacenter overheating incident. The maintenance had been tested and was expected to cause only a brief disruption. However, the switchover exposed additional instability under high load, and this forced us to remove some additional infrastructure from service and operate at reduced capacity for a time. We have now stabilized all Proton services and all are currently operational. No user data has been lost. We apologize for the disruption. --- [2026-09-01T19:26:18.342+02:00] (monitoring) 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. --- [2026-09-01T19:10:07.458+02:00] (identified) 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. --- [2026-09-01T16:59:34.045+02:00] (investigating) We are currently dealing with residual hardware failures that are likely related to the damage suffered from the overheating incident last week. At the moment we are operating at a reduced capacity, while our engineers work to bring additional infrastructure online. We apologize for the unfortunate timing of this incident and any disruption or inconvenience this may have caused you. --- [2026-09-01T14:37:58.835+02:00] (investigating) 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.
