We use DigitalOcean for our Management Nodes and Nameservers, we couldn't recommend them enough. Their support is fantastic, when we have had to submit a support ticket their replies were great and quick.
Their network and servers are great too! Fast networks and fast hardware allowing us to be able to monitor our networks and fast DNS Lookups.
We have a few VPS's with DigitalOcean and we wouldn't change to another provider, their control panel is easy to use and enables use to spin up a new droplet in under a minute.
I would recommend them to any business or person who are looking for a cheap VPS.
