This site is hosted at Netlify.
There are a lot of things that made a great impression to me before choosing it.
First, the free plan is very generous for free or commercial projects, with 100GB of free monthly bandwidth.
They include a global CDN, to make sure speed is not a concern even in continents far away from the central location servers.
You can point your DNS name-servers to Netlify and they will handle everything for you with a very nice interface to set up advanced needs.
They support having a custom domain and HTTPS —SSL/TSL security, with a full integration with Let’s Encrypt.
You can continuously deploy from Git across a global application delivery network. So just push your git commit to your Github Repo and Netfliy cares the rest.
