Last week we moved every certificate in one of our products to a new CA in 10 minutes. It was six certificates and 18 deployments. I said issuance was the part that slows down, because most CAs limit how fast you can order, and then I waved it off. A reader did the math for me. Some organizations run 30,000 certificates, they claimed, and that’s common at MSPs, telcos, and government agencies. Google Trust Services takes 100 orders an hour by default.
