Because the example is oversimplified for the sake of HN commentary. In the real world it goes more like this:
"Hey, I saw you patched that bug that was causing traffics spikes. That's awesome work and I appreciate your proactivity! The Ops team thought we had to work late tonight to implement mitigations for the problem.
In fact, it looks like we had a communication breakdown and they didn't realize you had fixed the issue until 6 hours later. In the future do you think you could let them know when this sort of problem is fixed, just to make sure we're all on the same page? We'll have to look at a solution
for automated alerts too -- maybe an integration with the ticket system or build system. Do you have any ideas for that so we don't have to rely on manual communication? We're moving so fast that it's hard for everyone to keep up! Thanks again for the great work."
