Is there any workaround for the following situation:
I work for a web consultancy and we have embraced LE fully and have setup many client sites using it. We have started to hit the rate limit lately and mainly because we use a naming convention of (f.ex) for internal purposes as well of client.prod.domain.com and the error is that there are too many domains lately registered for the domain.com.
This is true because when I check our domain in crt.sh I can see lot of renewals/new sub domains or sometimes expanding already existing subdomains with another domain. But if the domain.com exists in the certificate it may cause the rate limit to be exceeded.
Our last case in point was a situation where we had to expand the certificate by adding a new client domain to the certificate but our own .prod.domain.com was causing it to fail because for the last week too many domains have been already registered/renewed.
Because we have many different servers that host these sites I right now am clueless as how to approach this problem. Is there a way to separate the certificates into different certificate files? That way if we already have registered a domain.com subdomain it would not affect if we add a new different domain certificate to the server.
Right now if we expand it would update the existing one. Are there possibly plans in the future where companies can buy some kind of expanded limits? We just did not consider how these limits would start hindering our work when started to fully embrace LE.
