Case Study: AppNexus achieves reduced MTTR and reliable global ad delivery with Catchpoint

AppNexus - Customer Case Study

AppNexus is a global advertising-technology company that serves over 10 billion ad impressions per day, generating 150+ terabytes of data and peaking at 5 million transactions per second. That scale created critical performance and visibility challenges: they needed real-time digital experience monitoring across network and application layers, the ability to isolate first- vs. third-party issues, and trusted global validation of CDN providers to ensure timely ad delivery and protect revenue.

AppNexus partnered with Catchpoint to combine synthetic monitoring, real-user monitoring (RUM), behind‑the‑firewall Enterprise Nodes, advanced alerting, custom metrics/visualizations and the Smartboard for consolidated root-cause analysis. Today they run 700+ scheduled tests used by 500+ employees, can identify network issues in minutes, validate CDN performance, reduce MTTR significantly, and maintain reliable, high-performing global ad delivery.
