I used to use DO, but switched off after they decided to disconnect my droplet for 3 hours when it got DDoS'd. It didn't matter that my node was able to handle the traffic. I was only using it for a Mumble VOIP server and an IRC bouncer, so it's not like I was going to lose money by having some business going offline, but still frustrating and enough to decide that should I ever need to run an actual business, I definitely won't use DO for it.
