This article explains how AdTech companies can use Amazon CloudWatch Internet Monitor to optimize ad delivery by monitoring internet performance and availability across geographically distributed systems.

• CloudWatch Internet Monitor provides continuous visibility of internet conditions affecting ad workflows
• AdTech platforms require low latency and high reliability for real-time bidding and ad delivery
• Internet Monitor detects health events when network paths experience latency spikes or availability issues
• Alerts can trigger via CloudWatch alarms, metric filters, or Amazon EventBridge rules
• Example: New York DSP unavailability triggers Lambda to remove that DSP from bidding workflow
• Example: India path degradation detected via p90 round-trip time metrics triggers alternate CDN routing
• Granular RTT data in CloudWatch Logs enables custom metric filters for anomaly detection

Internet Monitor helps AdTech platforms maintain optimal performance by automating responses to internet weather events, reducing downtime and improving publisher and end-user experiences.
