What happens when the Bitwarden Servers are down?

I try to convince my friends and colleagues to switch to Bitwarden.
A colleague of mine asked me what happens if the Bitwarden servers are not available (but an internet connection is working).
Do the browser extensions have the data stored offline?
Can I log into my vault in the browser extension?

On Android I can open my vault when I have no internet connection (when I am in flight mode).
So here it is working when I am offline.

And what about the desktop apps?
Do they work when the Bitwarden servers are not available?


If am not wrong, until you have not logout from the extension or the desktop app, you can unlock then offline using your password. but dont know for how many days the your vault remind lock offline.

It stores a copy locally.
