Any devs out there with a Visual Studio/MSDN as subscription should also be aware of their free Azure credit. I get 50$/Mo, which is more than enough to host a static site with CDN (my blog typically runs at around 1-2$).
For how long? I remember I got something similar for AWS for a year. Hosted my Wordpress, year passed, then prices jumped up. I migrated to Netlify, rebuilding my site as a static one, hosted for free now.
