The ProtonMail onion service is a great resource to have. However occasionally I am unable to connect to it and instead receive an error of 'Onionsite not found', a timeout or similar despite requesting a new identity in Tor Browser which implies it is having an outage. In those cases the clearnet version of ProtonMail is functional and status.proton.me does not show any issues.

Guessing the status page infrastructure does not monitor the onion service? This should be rectified.
