Getting DDoSed is rare but highly destructive when it does happen if you happen to use something like Netlify. GitHub Pages is under fair use and only for personal projects (no commercial uses). For commercial use, something like Cloudflare Pages would be better. Cloudflare can also help with their whole suite of tools with mitigating attacks and they will call you if you do exceed the free tier according to this comment: https://news.ycombinator.com/item?id=39520894.
