> 1.5 petabytes of savings in data usage per day is not HN worthy?

Well it is, but the merit should come first to the engineers who implemented the Brotli algorithm. What Anamaria did was just to include the code for that algorithm in the Play Store. Sure, it's some good work, especially for an intern, but I think it's a big exaggeration to say that it is that work that saved 1.5 petabytes/day.

Deploying this at global scale was more than just changing some config and walking away. I'm sure things went wrong, changes had to be rolled back, lessons were learned. "just include the code", seriously, do you even deploy apps at scale?

You are perfectly right, and no, I haven't deployed anythong at the scale of Google. On the other hand, deployments at that scale are routinely done at Google, Facebook and Amazon amongst other tech giants, so an intern doing it shouldn't warrant an article.
