For the past two years or so, the website has been hosted on a Linode virtual private server. It’s worked well and I’d recommend Linode to anyone that asked. They aren’t too expensive, either: US$20 per month, plus an additional US$5 per month for a backup service for a dual-core affair with 2GB RAM and 50GB of solid state hard disk.
Now, however, I’ve switched to Online.net’s Dedibox XC, a server with 8 cores, 1TB of spinning-metal hard disk and 8GB of RAM. It’s a step up in hardware for me, for only €16 per month (which is about US$18, so just a bit cheaper than before). Plus it’s in France, which wouldn’t usually be a recommendation(!) …but in these post-Snowden days, it’s not to be sniffed at.
I believe everything has come across without incident, but if you spot anything missing, let me know.
