Apologies if they might have been answered elsewhere or if I might be missing something. I am interested in finding out more about the certificate limits and whether they apply per registered domain space, IP, or both. Referencing the below doc:
Some background, my company owns over 1000 unique registered domains. We would like to use Let’s Encrypt as our CA. The issue we are concerned about is getting these domains registered with Let’s Encrypt. We want to run a batch job to get them onto our hosts sourced from one server and will be running the requests several minutes apart. We likely will only need to make up to 5 requests per registered domain, although may consider wildcards or using SANs and roll it into one request.
I want to issue certificates for these domains and subdomains. My understanding is that if I reached the certificate limit for the list of registered domains per week, I could issue a total of 200 requests(50 requests * 4 registered domains). Or is this inaccurate and I could only issue 50 requests for the entire list of domains?
Thank you in advance for your help in understanding more about the rate limiting implications.
