No experience with DO, but RamNode is very good. I've been a customer for over a year, and I rarely had any downtime. Disk speed is between 300MB and over 1GB (on SSD), network speed can go over 70MB/s.

I have both RamNode and Digital Ocean servers in production.

In terms of performance and cost, both are great. I haven't ever had any issues with Digital Ocean. With RamNode, they've had a couple of issues where there's been minimal downtime. And they had a breach back in June, but responded well.

I think I trust Digital Ocean more. The setup is easier and performance maybe slightly better.

I used RamNode for a bit last year, but left them for DO after dealing with RamNode's servers getting DDoS'd constantly.

While I'm sure it happens with DO as well, at least there I don't feel like they're active participants in the various VPS provider feuds that you see all the time over at LowEndBox.
