The first Media over QUIC CDN: Cloudflare

Hi! Cloudflare MoQ dev here, happy to answer questions!

Thanks for the award, kixelated. xD

Is the load balancing of the relays out of scope? It doesn't seem to be addressed in the write up unless I missed it.

EDIT: Sorry I just noticed this was directed to Cloudflare. They're using the same architecture as Cloudflare Realtime, their WebRTC offering.

`relay.moq.dev` currently uses GeoDNS to route to the closest edge. I'd like to use anycast like Cloudflare (and QUIC's preferred_address), but cloud offerings for anycast + UDP are limited.

The relays nodes currently form a mesh network and gossip origins between themselves. I used to work at Twitch on the CDN team so I'd like to eventually add tiers, but it's overkill with near zero users.

The moq-relay and terraform code is all open source if you're super curious.

Home much success have you have with GeoDNS? We've seen it fail when users are using privacy respecting resolvers like 1.1.1.1. It gets the continent right but fails on city/state level.
