Case Study: Norwegian Cruise Line achieves website stability and zero downtime with New Relic

Norwegian Cruise Holdings Relies on New Relic to Bring Stability and Standardization to Its Website

Norwegian Cruise Line Holdings, a Miami‑based travel company operating 23 ships across three brands, faced a fragile, fragmented website that hindered bookings for guests and travel agents. Multiple disparate code bases, a slow industry reservations backend, and frequent crashes left uptime poor and the booking process unreliable—reaching a roughly 30% error rate when the in‑house team began diagnosing the problem.

By instrumenting the platform with New Relic APM and Browser, Norwegian gained end‑to‑end visibility, prioritized fixes, and stabilized the site within six months. The team consolidated to two primary stacks (PHP and Scala), moved to daytime, zero‑downtime releases, and embedded a data‑driven culture across QA and executives—resulting in faster innovation, better business decisions, and consistently improved website usability and reliability.
