I’ll assume that we are talking about issue certificates for subdomains of your main domain, i.e. (
server1.abcd.com, server2.abcd.com, serverX.abcd.com).
Yes, but, you should keep in mind that a renewal will count for that limit (there are plans to override this but in a future…). I mean, lets say you renew 50 certificates on Monday (I say Monday as an example, limits are not from Monday to Sunday but from last 7 days, it is a rolling limit), then you couldn’t issue a new certificate till next Monday, even worst, you renew 50 certificates on Monday, and another 50 on Friday… then you can’t issue new certificates till next Friday so if you plan to issue new certificates you should issue them before a renewal batch could hit the limits for that “week”.
I think so, as far as I know there is no limit on renewals, but @jsha or @cpu could clarify whether there is some high rate limit on renewals to prevent abuse.
The FAQ is suggesting to add several subdomains on the same certificate because if you add 100 subdomains in the same certificate, it counts as only 1 certificate but if you try to issue 1 certificate for every subdomain you will issue 100 certificates and all of them will count against the rate limit… and keep in mind that there is a limit of 50 new certificates per domain and 7 days.
That policy is for issue/renew the same certificate (a duplicated certificate). It means that you can’t issue the same certificate for the same subset of domains/subdomains more than 5 times in 7 days.
Maybe you should take a second look to the rate limit site and if you think it could be useful to you, then you could apply to a rate limit exception https://docs.google.com/forms/d/e/1FAIpQLSetFLqcyPrnnrom2Kw802ZjukDVex67dOM2g4O8jEbfWFs3dA/viewform but before apply, read very carefully all the doc.
