@dustinkrejci.primerica Overselling in a VPS is frequent in the low-price side of the industry, and decent performance/reliability over the course of 1 year is no definite indicate of long-term performance. It is not at all uncommon for providers to begin ratcheting up the server population only after they have gained some customers.
To be clear, I don't think this is what DO is doing. However, a little more transparency would help. Certainly they can give more detail than, "It varies, a scheduler handles it". They set the scheduler parameters, they can tell us if they allow the load average to stay around 10% utilization, 20%, 30%, etc., an average tenant load across all systems, and so on.
