Case Study: Arc XP achieves improved observability and a 15% drop in MTTR with Datadog

Reducing operational overhead and building value through improved visibility

Arc XP, an independent, cloud-native digital experience platform spun out of The Washington Post, powers thousands of sites and billions of monthly page views. Rapid growth and a distributed, polyglot microservices architecture made it hard to keep constant visibility across regions and meet SLOs—engineers lacked a unified, cloud-based monitoring solution with proactive alerting, so much time was spent on operations instead of building the product.

Arc XP adopted Datadog for its cloud-native, polyglot support, ease of use, auto-instrumentation, and customizable dashboards and alerts. The rollout of Infrastructure Monitoring, APM, and Synthetic Monitoring improved diagnostics and proactive detection, cutting MTTR by 15% in 2021 for teams using APM, reducing reported issues by 33%, lowering operational overhead, and letting engineers refocus on product development.
