Apache Web Servers and Power Failure

In the event of a sudden loss of power, an Apache Web server without UPS protection does not complete the steps it would normally take in order to close all open Web transactions and shut down: log files may be incomplete, incorrect, or corrupted. Thus administrators can lose critical transaction data (data upload or download transactions, etc.).

A protected Apache Web server that lacks automatic shutdown capability requires the presence of the Web administrator. In the event of a power failure, the administrator must quickly send a complex "kill" command to the server in order to shut down the software before the UPS stops supplying power.
