How to read this calendar
Dates use New York time (America/New_York). Green means no issues observed with sufficient monitoring coverage; it does not guarantee uninterrupted uptime. Pink includes official incidents, repeated website failures, or corroborated user reports. Gray days are unknown. Activity estimates alone do not turn a day pink. Today’s result can change.
ProtonMail website uptime and response time

95th percentile response time
0 failed checks; 0 restricted checks. Restricted checks are excluded from the success rate. Lines connect recorded samples across gaps; availability between checks is unknown. Response time measures receipt of HTTP headers, not full page load. Checks run from one US monitoring server and do not verify sign-in, API, or app features. These sampled results are separate from down reports and estimated activity.
Evidence behind the status
Website reachable in latest check. The public website responded; signed-in features and APIs were not tested.
Website checks and estimated activity have independent update times. Refer to each section for its latest observation.
These measurements describe different things. A reachable homepage can coexist with login or API failures. Missing evidence stays unknown.
Official component status
No mapped official components are available for this product. Parent-company status is not substituted for product status.
Official incident timeline
No product-matched incidents are available in the collected provider history. This does not prove that no incident occurred.
Recovery tracker
No recent recovery can be established from available evidence.
1 consecutive successful checks within the last 30 minutes. These checks measure the public website; they cannot establish recovery of every feature.
Slowdown detection
No sustained slowdown has been established against the earlier baseline.
Recent median: 677 ms · Earlier median: 802 ms. Flags require at least 3 recent and 5 earlier checks, more than twice the baseline, and at least 500 ms extra latency. Slowness alone does not identify server load as the cause.
Emerging down-report signals
No recent emerging problem patterns are available for this service.
Emerging problem patterns can persist after an incident and do not measure report counts or prove an outage.
Is it down in your region?
Run one public website check from a community probe. Results describe that probe, not every user in a country.
Results are reused for 15 minutes. Shared free allowance: up to 60 tests per hour. A successful website check does not verify authenticated app or API functions.
Infrastructure incident context
Check whether broader platform incidents coincide with the problem you are seeing. These providers are context, not verified dependencies of ProtonMail.
No active incidents recorded.

About ProtonMail status on Iszdown
ProtonMail is an end-to-end encrypted email service founded in 2013 in Geneva, Switzerland, by scientists who spent time at the CERN research facility. ProtonMail uses client-side encryption to protect email content and user data before they are sent to ProtonMail servers, unlike other common email providers such as Gmail and Outlook.com. The service can be accessed through a webmail client, the Tor network, or dedicated iOS and Android apps. ProtonMail is run by its parent company Proton Technologies AG, which is based in the Canton of Geneva. The company also operates ProtonVPN, a VPN service. ProtonMail received initial funding through a crowdfunding campaign. Although the default account setup is free, the service is sustained by optional paid services. Initially invitation-only, ProtonMail opened up to the public in March 2016. In 2017, ProtonMail had over 2 million users, and grew to over 5 million by September 2018, 20 million by the end of 2019, and over 50 million in 2020.
This page combines the available ProtonMail report activity, official product status, public website measurements, and daily history. Each measurement has its own observation time. A search spike alone does not confirm downtime, and a reachable website does not establish that sign-in or every product feature works.
No mapped official components are available for this service. Latest public website measurement: 2026-11-08T16:56:40.000Z.
What to check when ProtonMail is not working
These are troubleshooting suggestions, not a list of currently reported problems.
ProtonMail will not open
Compare your usual browser or app with a private browser window, then try another network if available. Save unsent work first. A difference between networks can help separate a local connection problem from a wider disruption.
ProtonMail is slow or only one feature fails
Record the affected action, exact error, and time. Compare the website response measurements with any official component incidents; loading a homepage does not test every feature.

Include the time, affected feature, and error message when contacting official support. Keep passwords, payment information, session cookies, and access tokens private.
Recent ProtonMail outage history
No product-matched official incidents have been archived for this service in the displayed history. This does not establish that it has never had an outage. See the daily calendar for other available evidence.
Frequently asked questions about ProtonMail

Why does ProtonMail show operational when it is not working for me?
An official operational status can coexist with a local network issue, account problem, or feature-specific incident. Compare the mapped components, recent incident updates, and regional diagnostic on this page. Automated website checks test public access, not your signed-in session or every ProtonMail feature.
When was ProtonMail status last updated?
No current product status observation is available for ProtonMail. Reports, estimated activity, and website checks can provide additional context.
Has ProtonMail had outages before?
The daily calendar links available incident evidence and retains daily monitoring summaries. Pink marks service issues, green requires sufficient observations with no issues observed, and gray means insufficient coverage. The collected history is incomplete and is not a lifetime outage count or a guarantee of uninterrupted uptime.
How do I follow ProtonMail or report a problem?
Use “Watch this service” to save ProtonMail in this browser’s watchlist, then return to compare its status with other saved services. Optional browser notifications can flag status changes while the watchlist page stays open and visible; background alerts are not sent. Use the problem-report button for an outage report; contact the provider through its official website for account, billing, or private support issues. Iszdown is independent and cannot resolve provider support tickets.
