I've got a user who is seeing
urn:ietf:params:acme:error:rateLimited: Error creating new order :: too many currently pending authorizations: see https://letsencrypt.org/docs/rate-limits/ on all of their requests across multiple servers and hundreds of domains.
I believe the issue was probably caused by an old version of the acme client (Certify) erroring somewhere in the process between starting a new order and before submitting challenges for validation. It could also be caused by things like running our of disk space or permissions changes etc.
My question is: if each ACME account is created independently, but they share the same email address, is there any pooling of rate limits? They're currently struggling to clear the limits and they're apparently also seeing the limits across multiple unrelated machines.
I can probably provide them a tool to just go through all recent orders and submit any pending challenges but the weird thing is that the rate limits appears to be spanning multiple accounts.
