What are blackouts and mains failures?
When the mains supply fails completely this is known as a total mains failure or blackout. Typical symptoms are a complete disruption of equipment operation. A break in the mains supply of only several milliseconds is sufficient to crash, lock or reset many of the components that make up a typical data or voice processing IP network, such as PC, terminal, console, server, PBX, printer, modem, hub or router. Common causes of blackouts are storms, lightning, wind and utility equipment failure. This typically occurs as a result of loss of power, a mechanical failure, or overloading by consumers.
