Abstract: Every major sales event turns the live room into a "battlefield" — traffic floods in within minutes, bandwidth spikes 10x instantly, and a single freeze means tens of thousands in lost GMV. This article summarizes the 5 most crash-prone areas during major sales and provides 5 battle-tested survival strategies: advance registration, bandwidth capping, adaptive bitrate, CDN pre-pull, and real-time monitoring alerts — helping you confidently handle million-level traffic in the next Double 11, 618, or New Year Festival.
