I have two servers A and B that connect via SSL to a third server X.
X had a new certificate installed recently.
Server A could not establish SSL with X, while server B is still working.
Server B is a production site and I am unsure why it still connects securely.
Is it possible that there is a persistent SSL connection that exists between B and X?
Once established, does the SSL connection still rely on a valid certificate?
I wonder about the risk of updating the trusted store of production server B during the holiday season, versus the risk of the server B SSL connection failing as happened with server A.
This is a highly visible enterprise site, thus my caution about the necessity of adding to B's certificate store and restarting services during this peak season.
