The panel's benchmark asks your server and our nodes for the same page at the same moment, and puts the two numbers side by side.
You run it on a zone whenever you like. Every node measures your server's response time and its own, and the panel shows them side by side, city by city.
On a real site of our own group, server wait went from 11.6 to 1.0 milliseconds: that is not a brochure number, it is what our panel measured, and you can repeat it on your own site in five minutes.
Bytes, requests and cache ratio per node and per day, with a count of how much traffic never reached your server at all. That is the number that says how much the CDN is doing for you.
Every site has its own availability page: the month's percentage, the minutes it was unreachable, the list of outages with time, length, nodes and cause. If we are below the 99.9% we guarantee, the page already tells you what you are owed.
Cache on the nearest node, Brotli compression, DNS answered from those same nodes that drops the ones not responding, and a network of twelve cities rather than one data centre.
