Ask HN: Global non-HTTP CDN provider

Can anyone recommend a service that:

1. Has great worldwide premium networking ( no Comcast! )

and either:

2. allows me to run a VPS at their edge locations

or

3. provides a service that allows me to connect back to our own DC via the proxy protocol

Context: tried a number of vps providers: vultr, linode, etc where I run haproxy but their infrastructure is flaky, there's no SLA. I need to proxy non-http traffic.

I checked out HAProxy Edge but their own network isn't very quick from the locations I'm interested in ( mainly Asia -> NA ).

I also checked out Fly.io but saw 5 errors in 5 minutes from trying to deploy an app/machine so I backed out.
