Hey @jgrahamc, just a heads-up, the output of the curl request in the "Using curl" section is not up to date:

  alt-svc: h3-22=":443"; ma=86400

I was surprise you didn't deploy draft-23 despite quiche supporting it, so I checked:

  $ curl -vs https://blog.cloudflare.com/ 2>&1 | grep alt-svc
  < alt-svc: h3-23=":443"; ma=86400

Could you pass it along?
