And lest Southern Californians get too sanguine, the probability is the same for a similarly strong quake there in the same time span.

With that in mind, IT managers at HOB Entertainment Inc. in Hollywood are discussing whether to replicate the company's data to a remote facility in Quincy, Wash., where it operates an amphitheater complex.

"It's a great location for collocation," said Adrian Black, manager of network operations in the department of information systems and technology at HOB. "That is such a remote location, and we own the buildings."

The Quincy facility already houses a T1 line, and a 100Mbit/sec. Internet connection is about to be installed there, Black said.

HOB, which operates the House of Blues clubs plus other performance venues, is concerned that an earthquake could cause significant damage to its headquarters in an 18-story building, Black said. He noted that the facility houses HOB's central IT operations and that the company's key financial, accounting, legal and marketing applications are all run on systems at the site.
