Serious question. What support would digital ocean , an unmanaged vps provider , really need to offer besides keeping their network, control panel and kvm nodes up? Assuming their infra is running normally which is a bare minimum there should be no reason to contact support.
-- they have large product set these days --
I've always found Digital Ocean to have such excellent documentation and usability that I've never had to contact support. Except a couple times to increase my number of reserved IPs which they did in less than 30 minutes or so
