When the Safety Net Snaps: How Miscalculated Failover Thresholds Turn Traffic Surges Into Infrastructure Crises
Most organizations design their CDN failover strategies for the traffic spikes they expect, not the ones that actually arrive. When surge volumes breach the boundaries of what a network was architected to absorb, the consequences extend far beyond slow load times — they expose origin servers, collapse redundancy layers, and threaten the very infrastructure meant to prevent outages. Understanding where these thresholds live, and why they are so frequently miscalculated, is not a theoretical exerc
