That's pretty major! I would definitely worry a bit about Vultr for production at this point. We are using it in this one instance for something internal that has a good amount of ability to go offline for a while without it being an issue. Vultr is saving us a fortune in this instance.
Amazon and Azure are really the big players now for production stuff. Rackspace is there but their quality is definitely lagging. We still use them (for ML for example) but are using them less and less. I've run into almost non-stop issues with using them for anything of scale. Their support is just so poor.
