A launch site that held up under real traffic

The challenge
Lumen had six weeks until launch and a site that took eleven seconds to load on mobile. A scheduled press feature was expected to send a large, mostly mobile audience in a single afternoon.
What we did
- Rebuilt the front end with static rendering and aggressive image optimisation
- Cut third-party scripts from fourteen to three and deferred what remained
- Designed a single-purpose launch page with the preorder action above the fold on every breakpoint
- Load-tested against a simulated spike before the press date rather than after
The outcome
The site held through launch day without a single error page, and mobile load time came down from eleven seconds to under two.
“We had one shot at launch day. The site never blinked, and preorders beat our internal forecast by a wide margin.”
