The exact words it rests on

our system “fails closed”, meaning that the Control Room integration in the engines is configured in such a way that if the Control Room service goes down, either due to a system error or because it is disabled for any other reason, including tampering by a bad actor, then all inference requests will be denied until Control Room resumes normal operation.
