Case Study: Türk Telekom achieves 70% faster issue detection and 60% less downtime with AppDynamics

How end-to-end visibility supercharged collaboration at Türk Telecom

Türk Telekom, Türkiye’s leading integrated telecommunications provider serving over 50 million customers with 30,000+ employees, faced operational friction from siloed IT and networking teams and a patchwork of monitoring tools. The lack of end-to-end visibility made root-cause analysis slow, increased unplanned downtime, and hindered customer-facing services and internal workflows.

Working with partner ONOTIO, Türk Telekom implemented AppDynamics’ application, infrastructure, and database monitoring to create a single, visualized monitoring platform with customizable dashboards and user-journey mapping. The consolidated solution eliminated siloes across departments, sped issue detection by 70 (cutting MTTR from hours to minutes), reduced downtime and service interruptions by about 60%, and enabled proactive improvements across the environment.
