Here is a list of the hosting providers I have considered or I am currently considering.
Scala hosting is my actual hosting provider. I have the Start Package (arount 11 US$/month). Unlimited sites, very fast at serving the website also in Europe, also very supportive. They offer Wordpress plans.
Only serves static files, it has a quite big free tier.
Fastly is the CDN that powers GitHub Pages. It is said to be incredibly fast.
