As of today, this site is now hosted by Vultr. I've been largely happy with several years of Digital Ocean hosting on this and other sites; however, Vultr offers a similar service at a lower price, so I decided to give them a try since I was already planning on migrating to a fresh-install Ubuntu 17.10 server anyway.
I have nothing but good things to say thus far. The web dashboard is pleasant and intuitive, and spinning up was very quick.
