The recent difficult circumstances for the residents of Houston allowed AboveNet the opportunity to provide customers the assurance of reliable, uninterrupted high bandwidth connectivity, while some local providers were experiencing network disruptions.

As Bill LaPerch, AboveNet CEO, said, "For us, it all starts with our focus on meeting our customers' needs, both during the ordinary business day and the extraordinary times experienced in Houston. We take seriously the trust our customers place in us to protect their vital communications, and to efficiently and quickly move massive amounts of data. In both normal times and extraordinary ones our ready-now processes enable us to best serve our customers."

A key element of AboveNet disaster preparedness, "expecting the unexpected," is being ready and able to respond to customer outages with effective, proven trouble-resolution techniques.
