There's two ways to react if an API you're using for authentication type stuff is down:
* Fail and essentially have downtime on the features using the API
* Succeed and essentially have no authentication for that time but no downtime
Parler took the second approach. Platforms that value security would take the first approach.
From the perspective of any company using a service like twilio (i.e., not just Parler and this specific set of events), would there not be some sort of failsafe in case something just like this were to happen? Or would this kind of thing be so nearly inconceivable that you wouldn't protect against it?
