Yes, as the certificate are in the public domain anyway. However, certificates are useless without their corresponding private key and those are NOT in the public domain, obviously.
You can restore your certificates by downloading them from sites such as https://crt.sh/ and fetch the corresponding private keys from one of your recent backups.
Thanks for your prompt advise. I have a feeling this was not backed up. In case there is not a backup, any idea of how long of a wait there is for the next cert activation ?
