That page does not support the statement that they moved off Django to Flask.

It further links to this post:

> They started with Django but moved out of Django and currently use 'home grown framework on top of Flask'.

But it supports that they do use Flask.

> Presently, the API does over 12 billion requests per day, all in Flask.

Wow, that is 138kqps. Not something that would strike me as your typical Python workload.

There are lots of those lying around.

I don't know if it still is, but when I was at Mozilla the service that every instance of Firefox around the world hits to do the version/extension-compatibility checks was backed by Django, and was at something like 15k req/s served. Firefox has gained some market share in the four-ish years since I got that number, so probably larger now.

Whacking great big CDNs in front of your infra will do that.

What exactly a CDN can do to increase the qps throughput of your backend? I thought it's used to reduce it...
