					Mark all public keys from the given remote instance as expired.

					their keys for whatever reason (security issue, data leak, routine
					safety procedure, etc), and your instance can no longer communicate
					with theirs properly using cached keys.
					<br/>
					A key marked as expired in this way will be lazily refetched next time
					a request is made to your instance signed by the owner of that key.
