How One Engineer Fixed a Cache Poisoning Nightmare
from The Software Engineering Podcast with Fexingo: Code, Architecture, and Engineering Best Practices Hosted by Fexingo
In this episode, Lucas and Luna dig into a real-world cache poisoning bug that took down a major e-commerce site for six hours during Black Friday. They walk through how a single engineer—backed by a small team—traced the root cause to a misconfigured CDN caching rule, then deployed a fix that cut page-load times by 70 percent while preventing future incidents. Along the way, they discuss cache keys, surrogate keys, and why 'the cache is the hardest problem in computer science' is more than a joke. If you've ever hit F5 and seen someone else's shopping cart, this one's for you. #CachePoisoning #CDN #WebPerformance #BlackFriday #SiteReliabilityEngineering #SoftwareEngineering #Technology #FexingoBusiness #BusinessPodcast #CacheKeys #SurrogateKeys #Ecommerce #ProductionDebugging #Latency #EdgeComputing #CDNMisconfiguration #LucasAndLuna #EngineeringPodcast Keep every episode free: buymeacoffee.com/fexingo
