From their status page: "We’re aware that a small number of users may be experiencing issues."

The status page literally looks like a Christmas tree. Mail, VPN, Calendar, Drive, Docs, Pass, Wallet, and "Lumo" (whatever that is) are all bleeding red. The only thing fully operational is proton.me, presumably because the landing page with the "Upgrade to Visionary Plan" button must never, under any circumstances, stop rendering.

Partial outage? No, that is not good enough.
