What Hacker News says
3 sourcesThe Push Server [0] and ap-loadtester [1] both use PyPy. I believe it's in use elsewhere as well but that's what I could dig up quickly.

In Mozilla Awards $585k to Nine Open Source ProjectsI believe my article on Hacks (https://hacks.mozilla.org/2016/01/web-push-arrives-in-firefo...), linked from the marketing article, answers all of those questions at a high level and points to docs with more detail.
In short, there's a single, persistent websocket connection between you and a broker service run by your browser vendor. Each subscription has a unique, anonymous URL on that service that gets provided to the website. To prevent abuse, there are throttles / quotas / limits imposed on push messages that do not show user-visible notifications.
The source to Mozilla's broker, autopush, is at https://github.com/mozilla-services/autopush. We recently rewrote it from Go into Python, which we now run with PyPy in production.
