UPDATE: "We have identified a critical cooling failure in our Frankfurt datacenter. We are currently in the process of shifting traffic to our backups sites."
Last thing I saw before my Proton Mail stopped responding was the "how are we doing?" survey modal, which I dismissed because I just wanted to get to my email.
How is it the browser extension doesn't have a local cache? It seems like basic functionality. I'm having to copy passwords by hand from the mobile app, which does have a local cache.
Anyway, it's a good reminder: self-host all the things!
Mine does. I am able to login to the browser extension with my password and see all my passwords. I think there was a setting to enable local caching somewhere.
I have to admit, this one has pissed me right off. I build systems that survive datacentre failures all the fucking time, it's inexcusable that a single site going dark removes access to something I pay like 200 euro a year for.
Just for anecdata: I'm using simplelogin to alias my emails and I can see there is a 20ish minute window between when Simplelogin receives an email, to when it finally shows up in my Proton inbox. Normally it's an inconsequential delay.
Not sure if that indicates how much of a backlog of emails Proton has because of this outage, or if the DR infra is just that much slower?

>> Browser Extensions: Major Outage
A nice reminder to keep passwords offline.

And it's enabled by default.
