What Causes Websites to Crash Under High Traffic ConditionsWebsites crash under high traffic because the infrastructure and application code can’t handle the sudden surge of simultaneous user requests. How to Simulate High Traffic Scenarios in Performance TestingSimulating high traffic requires realistic test scripts that mimic user behavior, session management, and request diversity. How Continuous Load Testing Supports Agile DevelopmentContinuous load testing fits agile’s iterative nature by providing rapid feedback on performance impact of incremental changes. Session replication or stateless tokens (e.g., JWT) improve scalability and reduce crash risk under user load. As traffic becomes more unpredictable, combining continuous load testing with DevOps workflows and using fault-tolerant infrastructure is no longer optional.
