When Smart Routing Turns Against You: The Hidden Cost of CDN Cache Competition at the Edge
Modern CDN routing algorithms are designed to accelerate content delivery, but under certain load conditions, their own intelligence becomes the source of measurable delay. Cache thrashing, staleness conflicts, and resource contention at shared edge nodes are creating performance paradoxes that most infrastructure teams never diagnose. Understanding where optimized logic breaks down is the first step toward reclaiming the speed your architecture promised.
