Why does Cloudflare Tunnel use HTTP/QUIC instead of WireGuard?

According to this article:

The initial version of cloudflared uses HTTP/2 frames, with a QUIC implementation being added a few months ago.

I’m curious why Cloudflare uses transport layer tunneling as opposed to the more performant WireGuard? Especially considering WARP uses WireGuard.


Cloudflare tunnel predates Warp by several years. It also maintains redundant connections per data center to 2 data centers and only routes traffic initiated from edge to origin.

I’m not as familiar with WireGuard. Can you not have redundant connections?
