Reading the service alert, it looks like you need to worry about this ONLY if you are running your own SENTINEL server (not using AIS', something I didn't even know was an option). That should have been spelled out in the message, which I initially took for somewhere between mistake (optimistic) and malicious (pessimistic). " Clients of AIS who have servers with Sentinel installed that are not housed with AIS will need to upgrade themselves." That doesn't answer "Why isn’t AIS using a recognized certificate authority with root certificates that computers already trust?" But 50% isn't bad, right?
