Like many people these days I have various bits of infrastructure and software that I run to support internet services for my own personal domains, mostly email, DNS and web. I have a physical server colocated in a datacentre that hosted much of these services, but the colo costs have become quite expensive and running my own hardware is a bit of a liability. So I have been slowly moving all my stuff to AWS, which is the cloud hosting provider I am most familiar with.

Domain fronting is a technique that allows circumventing HTTP domain restrictions by leveraging the fact that some large web content providers do not check that the domain specified in the Host: header of the HTTP request matches the server_name in the TLS handshake.
