What's a hack in your industry that customers aren't supposed to find out?
I don't work there anymore, but I used to work for a cable internet ISP. You weren't supposed to know this, but when customers complained about slow hardwired speeds, we'd show up and pretend to do something, knowing full well that the issue was our nodes being oversaturated everywhere. But we would never tell you. We eventually introduced something called "Power Boost" to mask the problem by skewing speed tests. Your first 5-20 seconds would be uncapped bandwidth and you would think you were getting a quality product when you weren't.
I kinda figured this out on my own. I used to be pretty versed in how tech worked and when my parents were getting about 1.5mbps off cable Internet they called to have a guy come check everything out.
Guy shows up and “does some work”, comes in and does the speed test on his work laptop, comes back 40mbps (this was high speed back in the day). My parents were super excited but I, a teenager, was like “Hang on. Don’t leave yet. Can you do that speed test through Ookla? I’ll do one after you do just to confirm it.”
Never saw a grown man start to sweat so fast.
