Moving to TLS 1.3 and HTTP/2

Last updated: this month

We've finished upgrading our edge stack to TLS 1.3 only and enabled HTTP/2 across all sites. Latency and security both improved. Cipher suite in use: TLS_AES_256_GCM_SHA384 and TLS_CHACHA20_POLY1305_SHA256.

Nginx and reverse proxies

Single nginx instance in front of several backends keeps config in one place and centralizes SSL termination. We use long timeouts for WebSocket endpoints so connections stay up.
