Chasing the Ghost

Chasing the Ghost

Sometimes, somewhere, for some small but growing percentage of your users, your site is unbearably slow. Your server log shows no signs of trouble. Pingdom doesn’t report anything unusual. You run a few load tests - all seems well. But the complains mount up. WTF is going on? A true story of how I tried to chase the latency ghost haunting one of our projects and what I’ve learned from it.
