I'm a fan and daily user of Signal, but here is the harsh reality that this outage (going on for more than half a day now) exposes: Signal is not, today, suitable as a primary secure communication channel. Maybe one day when it scales, but not today. Countless critical conversations were disrupted today.
Signal has critically failed two times in the past year: now, and almost a year ago when they were forcing everyone to create a PIN (and subject their data to their weird SGX-based cloud storage thing) despite users yelling at them how bad of an idea this is. If you didn't want to do it, you were locked out.
That one pissed me off a lot more than today's outage, which is understandable, hopefully short, and unlikely to be repeated once they get scaling under control. It's also the reason why I'm not donating today.
