We experienced some users having issues signing up for new accounts between 17:30 and 19:45 UTC. During this time, some new users were unable to sign up for Proton Mail, Proton Drive, and Proton Pass due to a false positive of our anti-abuse system. It did not affect any existing users -- it only affected those signing up for a new account. Refreshing your browser will fix the issue. We apologize again for the inconvenience. We can confirm no data has been lost.
