> If you want some serious redundancy nothing beats running services anycast with BGP across multiple cloud providers.

Unless they're TCP services. Or stateful UDP services. Then you're in for a world of pain if you try to anycast them.

The list of sensibly anycast services is surprisingly low. Stateless UDP services, essentially, which isn't a big list. Especially if you're the kind of person who's using Vultr's cloud, and not a megacorp.

If you have the resources to develop backend state sync, you're probably still better serviced with a (set of) load balancer(s).

No way. Stateful TCP over anycast works fine reliably to many nines.

I run a CDN with anycast BGP, this obviously uses TCP. Works great. I've also done it with a global network of physical datacenters and our own transit/peering network but eventually migated to the cloud for reasons.

Do you know of any other providers with at least the same quality that Vultr offers that offer BGP?

This is absolutely awesome. I'm not sure if you're a maintainer of this list, but, this is VERY useful. You just found me a provider who is scratching an itch for a specific niche location which I've had for years. I owe you a beer or three.

Packet/Equinix Metal, but, they are much more expensive.
