The story
A band site has a strange traffic shape. It does almost nothing for weeks, then a single post goes out and several thousand people open it inside an hour, all wanting the same three things: dates, tickets, and whatever just got released.
It is also, by nature, a page full of other people’s embeds — a video, a streaming player, a ticket widget, a merch link — each dragging in its own scripts before anything is readable. On announcement day that is the worst possible combination: peak traffic across the heaviest page you own.
Turning the video into a click-to-play poster, delaying the third-party players until someone actually wants them, and serving the whole thing as prewarmed static HTML changes the shape entirely. The spike lands on a page that is already built and already light.
