The power of the edge

Our real-time “Tachometer” displays Requests per second, Cache hit ratio, Hit time, and Bandwidth based on aggregated requests and bandwidth across our network. These figures include usage and services from all of our customers, as well as trial, developer, nonprofit and open source program, and other non-paying accounts. These figures also include usage from our own internal health check requests. As such, these figures are only for informational purposes to show the scale of our network and do not reflect or predict our revenue or financial performance. You should not rely on our Tachometer to evaluate our business or expected financial results.

Requests per second

This is a count of every request across our network in the last second.

Cache hit ratio

This is the ratio of cacheable content served from cache to cacheable content that needed to be fetched from a customer’s origin. Cacheable content is defined as content that has not been explicitly marked to always be fetched from the origin.

Hit time

The average amount of time it takes to serve a piece of content that is cached on one of our servers.


This is the current aggregate size of all content served from all our servers in the last second.
