Triangle Man is a decent front end designer, but he knows nothing about networks. He keeps having to make this point because he has built Vercel on top of AWS which charges him for bandwidth so he has to pass that cost onto his customers or he'll go bankrupt. Cloudflare, on the other hand, built our own network so bandwidth is largely free for us. The best judge of the 'quality' of bandwidth is how peered an organization is. Here's a list of the most peered networks in the world:

That means that the default bandwidth you get for free from Cloudflare is actually more likely to be fast and reliable than the Amazon bandwidth you pay for from Vercel
