Does the secret manager work offline to some extent?

I work at a medium scale ISP and it’s considered a good practice to code our tools and automations in a way that they are able to work without an internet connection. Currently we’re using ansible vault to distribute secrets in a static way, meaning that secrets updates have to be delivered by running playbooks to copy the new secrets to the target applications. Does the bw secret manager cache the secrets in an encrypted form so that they can be accessed while the bw server is under maintenance or unreachable for some other reason?
