Other countries we check Proton Mail from
How we measured this
The US readings on this page come from RealUptime's own Ashburn and San Jose probes against Proton Mail's public endpoints. They are not user reports, and they are not Proton Mail's own status page.
See Proton Mail's full check readings, the 90-day history by region, or the outage tracker methodology.
The US readings here are taken from that country and show the time of the last one, but Proton Mail has not yet accumulated enough continuous history for us to publish this page to search engines.
