I'd draw people's attention to https://www.reddit.com/r/redditdev/comments/13wsiks/comment/...

> On March 14th, Apollo made nearly 1 billion requests against our API in a single day, triggered in part by our system outage. After the outage, Apollo started making 53% fewer calls per day. If the app can operate with half the daily request volume, can it operate with fewer?

That's a backend server making a request that doesn't count against its rate limit as soon as it can again.

The push notification backend is described as making a request every 6 seconds for each user. If it isn't backing off correctly and delaying a requeueing of the next job, that can drastically increase the request rate.
