It will be interesting to see. Just for completeness, Fastly is not requiring us to BYOIP or anything unless it causes them actual problems, which so far it hasn't. I'm sure they also have other similar businesses to ours so they should have some experience.

I guess I'll see in a while if this was also just a sales tactic from Cloudflare or not.

Yeah, I also assume that any sane CDN of this size has enough IPs that they can reserve a /16 or so for their "risky" customers (each deployment needs a /24, usually, so /16 gets you 255 regional sites). If Fastly has no problems or can otherwise quarantine you, there's no good reason for the BYOIP demand.
