ColoServe`s San Francisco data center maintained its 100% facility uptime record during a transformer explosion that darkened the building and affected other adjacent colocation facilities.

On Tuesday afternoon at approximately 4 PM, there was an explosion of an underground PG&E transformer at the south west corner of Spear and Harrison streets in San Francisco. A loud pop was heard, and all the CRT screens in ColoServe`s office space across the street were affected by a powerful electromagnetic surge. The cement sidewalk cover over the transformer was even shattered due to the force of the explosion pushing upward.

Power was lost to the ColoServe building at 360 Spear Street, including hallway lighting and the JMA Wired colo facility on the first floor, but ColoServe`s facility was unaffected. This is because ColoServe`s facility shares dual power grids and backup generators with MCI, and is fed by two private feeds using separate trenches from PG&E.

PG&E crews were on site within minutes, and power was restored to the building roughly an hour later. The outage at the JMA Wired facility was traced to a problem with the automatic transfer switch, which failed to engage to switch from utility to generator power after the explosion, but was resolved in about 30 minutes.

ColoServe`s San Francisco colocation customers were unaffected by the explosion, with no power interruptions or spikes, and maintained 100% uptime during the unusual incident.
