We're having fun figuring out how to communicate amongst colleagues now! It's when it's gone when you realise your dependence
As a degraded-state fallback, email is what we're using now (we have our clients configured to encrypt with PGP by default, we use it for any internal email and also when the customer has PGP so everyone knows how to use that)
Admitting to that here?
In civilised jurisdictions that should be criminal.
Using cryptography to avoid accountability is wrong. Drug dealing and sex work, OK, but in other businesses? Sounds very crooked to me
if you seriously have no external low dep fallback, please at least document this fact now for the Big Postmortem.
When Slack was down we used... google... google mail? chat. When you go to gmail there is actually a chat app on the left.
