What brought it closer to home was the characteristics of the recently affect site (same number of daily visits, not popular (a bit niche), etc) where similar to mine.
Moving is easy enough, mostly requiring a DNS update, since I prefer to build the HTML locally and then just dumping it somewhere.
What struck me as odd, when looking for an alternative is that almost none of the popular solutions Netlify, Vercel, Cloudfare (AFAIK) actually implement a spend limit.
This seems like such a basic thing to do...
