first, we were absolutely happy about let’s encrypt, because we hoped to offer ssl to our customers.
We are developing hosting services for our customers and we want to give them free subdomains for a quick start, like customer1.example.com. Unfortunatelly, after one or two customers, this rate limits occurs because its counted on our parent domain.
Is it possible to whitelist some domains? Maybe with reasonably explanations.
Alternatively to change this rate limit to certs per domain and user? Because our customers should create the certificates themselves? (Ok, we are currently in an alpha stage, but we want to know if its good to implement)
For us, its a great advantage of let’s encrypt to sign subdomains. But with this rate limit we can’t offer encryption to our customers (let’s encrypt has a rate limit and other providers are too complicated and doesnt allow subdomains without parent domain).
