🚨📺⚡The failures that take down a live stream at peak don't show up in normal operation. That's exactly why they get shipped. Five patterns we see break OTT services at peak concurrency, and the test for each before kickoff: 1. Origin manifest spikes. At low latency, manifest requests can spike faster than segments. Load-test manifests separately, at your real refresh interval. Watch p99 manifest latency, not the mean. 2. ABR collapse on shallow LL buffers. Tune ABR for the low-latency profile, per player. Test under packet loss, not default conditions. 3. Ad-marker drift. It's a replay problem. Validate marker-to-segment alignment on start-over and catch-up, not just live. 4. Regional cache exhaustion. Viewers cluster geographically. Model cache fill per region under clustered peak, not global average. 5. STB re-buffer storms. A one-second blip can trigger a synchronised reconnect bigger than steady-state peak. Test the recovery spike, not just the outage. The theme: every one is invisible at average load and obvious at peak. That's why they ship.
