I've been hosting one of my larger sites (multiple frontend, backend and load balancers) on DO for years. This is the first major outage I can recall, and it only lasted 10 minutes. I've had more downtime on AWS.
Of course they (we included) do.
Is the implication no-one should?
Well I guess it would vary depending on the criticality of your services but I've always been skeptical of running production workloads based on a number of reviews I have read in the past. For testing and development they have been great for the price.
