An automatic elevator safety system (1) includes an elevator safety circuit (17) and an external server (22). The elevator safety circuit (17) is configured for monitoring the operation of an elevator system (2) comprising at least one elevator car (6) traveling along a hoistway (4), and an elevator control (13) configured for controlling the movement of the elevator car (6). At least one of the elevator control (13) and the elevator safety circuit (17) is configured for sending data comprising information about the current state of the elevator system (2) to the external server (22), in particular in case a safety issue has been detected. The external server (22) is configured for (A) receiving the data sent by the at least one elevator safety circuit (17); (B) analyzing the received data; and (C) depending on the result of the analysis, sending commands to the elevator system (2). The commands include instructing the elevator system (2) (a) to ignore the safety issue and to resume normal operation of the elevator system (2); (b) to operate the elevator system (2) in a restricted rescue mode; or (c) to stop operation of the elevator system (2).
