up.kpop.re does 100mbits for me surprisingly now, half of year ago I've constantly seen 20-30mbps, especially in peak hours
maybe ISP fixed something, or because of corona, or just accidentally, not sure
but I've seen a lot of users complaining because of the low network speed of that ISP
you probably won't see much benefit if your network channel is 100mbps though, and cloudflare doesn't cache video
