Anyone serving requests with HTTP/3? How was your experience?

  @SpartanHost DDoS protection service blocks high-rate UDP, which disrupts HTTP/3.
  Sad.

  Nope not yet. Server is still on HTTP/2 but I think Cloudflare serves HTTP/3 from their side.

  Recent nginx 1.25.0 release added experimental HTTP/3 support. Anyone using it?

  For 3+ years now been testing various Nginx HTTP/3 implementations from Cloudflare quiche based HTTP/3 with BoringSSL https://github.com/centminmod/centminmod-caddy-v2#http3-https-tests and Nginx's implementation with quicTLS OpenSSL forked implementation. Nginx's HTTP/3 implementation isn't as mature so it's only been for testing and not for production yet. If you want HTTP/3, just use Cloudflare with HTTP/3 enabled in front of your server. Nginx origin servers don't need HTTP/3 in that case behind Cloudflare since they only connect to origin servers via HTTP/1.1/2.

  Last tested on latest Centmin Mod LEMP stack beta with AlmaLinux 8 and Nginx 1.23.4 https://community.centminmod.com/threads/official-nginx-http-3-quic-tech-preview-announced.19865/page-2#post-96340

  But also tested on Nginx 1.25.0 with quicTLS for HTTP/3. Centmin Mod Nginx supports various crypto libraries like LibreSSL, OpenSSL 1.1.1/3.0/3.1, BoringSSL, quicTLS and CF Quiche so makes it easier to switch and test various HTTP/3 QUIC implementations.
