Hennegan was motivated not just by concern for the executive's well-being, but also by the fact that the president was one of only three people at Gilsbar who were authorized to call SunGard Availability Services, the third-party insurance administration firm's IT hot-site vendor, and declare a disaster.

In addition, there weren't any working landline or cell phones within 50 miles. As a result, it wasn't until 3 p.m. on Wednesday, Aug. 31 -- two days after Katrina struck -- that Gilsbar was able to make a disaster declaration to SunGard. And then the company was thrown a curveball: Although Gilsbar had always run its disaster recovery tests at SunGard's Alpharetta, Ga., facility, it was assigned to a hot-site facility in Chicago -- a 14-hour drive away.

In preparation for this year's hurricane season, Gilsbar has made some changes that are designed to help get its systems up and running again within 48 hours of a disaster. If a big storm is forecast, the company will pre-position an IT team in another location, such as Memphis, with a set of backup tapes, Hennegan said. Those workers will be authorized to declare a disaster and start recovery procedures at SunGard, he added.

Despite the challenges that Gilsbar faced in the aftermath of Katrina, Hennegan said SunGard's hot-site service "is fabulous for us." He also praised SunGard for helping with non-IT needs. "People came up with their families," he said. "Some of them didn't know what their home situation was, and they were emotional wrecks when they got to Chicago." SunGard made sure that everyone was fed and that activities were organized for the children, he said.

But not everyone shares Hennegan's view. For example, the series of hurricanes that hit the East Coast two years ago encouraged Greg Holdburg, manager of disaster recovery and business continuity services at S1 Corp. in Atlanta, to move away from SunGard as a hot-site vendor.
