Shipping Media Over QUIC at Meta Scale for Instagram Live Ingest

Instagram Live ingest moved from Meta's in-house RUSH protocol to the open IETF Media over QUIC standard on iOS and Android. Edge endpoints translate MoQ frames into the RUSH format, so the backend did not change. Server-side routing let the experiment resize in minutes, the transport falls back to TCP when UDP is blocked, and the launch matched RUSH on quality and reliability.
