I've been with Digital Ocean for over a year, and I'm fairly certain that I haven't had any downtime at all. The site is used by thousands of users a day, and I've never had any complaints. Pingdom is set to a resolution of 1 minute, and hasn't reported any outages either (that weren't caused by me).
We run our forums on DO as well and it hasn't caused a hiccup at all. Uptime has been great for me, but at this point there isn't enough tooling around DO for me to be comfortable with doing more than just simple web sites
