This is great, I use LetsEncrypt for my company. however, the graph is a little misleading. Lets look closer:

LetsEncrypt is almost built upon the idea of frequently (and automatically) re-issuing your certificate(s). The graph's line shows what appears to be an accumulated sum of certificates issued by day.

If every 90 days most certificate(s) expire, of course the graph will look like that!

Whats most interesting to me is the steps up in the graph. It appears that the steps in the graph roughly occur on 70-90 day intervals.

Impressive growth for a great mission/service, but I wanted to point out the mechanics behind the graph. Hopefully others can offer some alternative perspectives!

edit: Grammar, illogical sentence structure.
