I've run IRC bots on several VPS services, and connectivity on DO was by far the most unreliable. It's crazy how often they would randomly drop out, even under no load.
With DO we'll have some clients seeing great performance, and others who may as well be on a spotty dial-up connection at the exact same time. Frustrating, and there's not really anything you can do about it except switch to another host. I'd love to know what the story is with 'em.
