Right now, I would only switch from Bunny if they allow IPv6-only origin servers and route IPv4 traffic to it.
Also no pricing and a "Talk to sales" only link. Which usually means super expensive, or B2B only. I pay like 10 cents a month on Bunny something
Ah yeah I see CDN77 has no signup button and just says "Talk to sales" instead. That's not helpful to small self hosters.
