DO has huge reliability issues, particularly in NYC. Over the course of several months I had repeated brief network drops on random VMs (during EST business hours, lasting up to a couple minutes). Their object storage in NYC3 (only location at time I used the product) would constantly drop uploads of larger files (experienced in multiple locations behind different firewalls, not environmental) and was also down for several days at one point not too long ago.

Perhaps things have improved, or my experiences with roughly 20 VMs distributed between Toronto and NYC was abnormal given the overwhelmingly positive sentiment in this thread but I figured I'd offer my $0.02 if only to play the contrarian.
