<p>Category fixes</p> <p><b>New page</b></p><div>{{update|date=25 August 2003}}<br /> <br /> I apologise for the problems with the San-Franciso servers today. The problem has now been fixed and the servers should be functioning normally again.<br /> <br /> The following is an overview of events leading to the outage and subsequent restoration.<br /> <br /> # On August 24, 2003 at approximately 1:30 PM PG&amp;E experienced a power failure on the lines servicing the San Franciso hosting facilitiy<br /> # At this time the facility went on UPS Power and then subsequently generator backup without incident.<br /> # This backup continued to run until August 25, 2003 at 2:47 AM when a component in the generator itself failed. The component that failed is known as a CT and monitors power within the generator. Due to a manufacturers design problem, the CT was not physically restrained to prevent possible movement within the generator.<br /> # At some point after running for 14 plus hours the CT physically spun inside the generator causing a physical short between two of the electrical phases, which in-turn caused several of the control boards to fail. With built in safeties, the generator shut itself down.<br /> # The Building Engineering staff was notified that the generator failed and they started repair efforts. The generator technicians were called and dispatched to the facility.<br /> # At 7:30 AM PG&amp;E dispatched a truck to reconnect the facility to the power grid.<br /> # At 8:03 AM PG&amp;E reconnected the power grid and power was restored. <br /> <br /> [[Category:Technical updates|{{PAGENAME}}]]</div>
