Also, PoPs in some regions are often nearly useless even if they exist on paper.
For example, Cloudflare has a PoP in Seoul, but it has such limited bandwidth that most sites using Cloudflare are routed to Tokyo, Hong Kong, and even Los Angeles. Several of my clients in Korea signed up for Cloudflare a few years ago when the local PoP was still usable, but now all but two of them have canceled their subscriptions. Instead, I've been building a lot of caching proxies for them lately.
If anyone is here for the Winter Olympics right now and some of your favorite sites don't seem to be living up to Korea's reputation for ultra-fast internet, Cloudflare might be one reason. (Meanwhile, Amazon's PoP in Seoul is perfectly fine, albeit expensive.)
