Thanks! I'm aware of them, but you need two peers to be able to announce your IP space (multi-homing requirement). AWS actually also allows you to bring your own IPs, so we might indeed go Vultr+AWS for now.
It’s only the RIR which requests proof you will multi-home and you must have been able to say to which AS you would peer to get the /22, since it’s a question RIPE asks as standard and the analyst will have considered in approving your application.
BGP itself doesn’t care at all. Announce the entire block from one “region” in Vultr, or split it out with a /24 in four different ones. It’ll work just fine.
I dont think the multihoming requirement works like that. Either Vultr or AWS would fulfill it, as they each certainly would be advertising the block out several redundant ISP paths, thus fulfilling the multihoming justification...
Vultr can do so https://www.vultr.com/features/bgp/ for no additional cost.
