Challenge
The store handled ordinary traffic and collapsed on the first day of a sale. Product pages took over four seconds, and checkout failed silently under load with no message a customer could understand.
Solution
We separated the storefront from the order system, added pre-rendering with incremental revalidation, and rewrote checkout as a single resumable transaction. Every failure now shows a message explaining what happened and what to do next.
Impact
Peak became a commercial event rather than an engineering one, and the team stopped spending launch nights watching dashboards.
