IRVINE, Calif., February 24, 2004 – VitalStream®, Inc. (OTC: VSTH), a global provider of integrated content delivery services, and RouteScience, the leading provider of adaptive networking software (ANS), announced that VitalStream selected RouteScience® ANS to optimize the performance of the award-winning VitalStream content delivery network.

"This announcement further underscores VitalStream's commitment to provide its customers a highly efficient network to deliver their media faster with less buffering time."

"Since VitalStream implemented RouteScience ANS we have seen up to a 300% increase in overall average network performance for our customers' streams and websites based on monitoring and metric reports from the RouteScience software," said Steve Smith, chief technical officer of VitalStream, Inc. "RouteScience ANS is well-suited for VitalStream's multi-carrier network because it gives us the ability to proactively route traffic to the best performing network, at any given time, in real-time."

"Network uptime and performance are the top considerations for businesses seeking content delivery and streaming media services," said Paul Summers, president and chief executive officer of VitalStream, Inc.
