CyrusOne Delivers Uninterrupted Service During Hurricane Rita; CyrusOne Implements Emergency Management & Response Plan for Hurricane Rita and Reports 100% Uptime

Business Wire, Sept 27, 2005

HOUSTON -- CyrusOne (www.cyrusone.com) initiated its Emergency Management & Response Plan for Hurricane Rita on September 17th, 2005 when the National Oceanic & Atmospheric Administration first announced that a low pressure system was expected to move into the Gulf of Mexico and become a full-blown hurricane.

Throughout the week of September 19th, the CyrusOne Emergency Management Team monitored all severe weather threats from its emergency management command center in Houston, TX, and worked with both customers and non-customers to implement their disaster recovery and business continuity plans.

When CyrusOne implements its emergency management plan, it ensures six important areas are addressed before disaster strikes:

Health & Safety - The health and safety of our customers and staff is CyrusOne's first priority. We work with customers to ensure their disaster plans are in place and activated. All customer temporary office space was secured and physically monitored throughout the storm.

People - CyrusOne ensures that it has proper availability of staff. More than 40% of the CyrusOne staff were on-site and running operations 24/7 throughout the storm, ensuring 100% uptime. Communications and preparation guides were distributed to all on-site visitors and employees.

Facility - CyrusOne guarantees a secure facility, even in extreme conditions such as a hurricane. Both logical and physical security of the facility was fully monitored and managed 24/7. Five zones were established in the facility and the physical integrity of each zone was monitored every fifteen minutes.

Operations - All mechanical, electrical and fueling processes are reviewed and activated during an Emergency Management Response. Uninterruptible power and cooling systems, including generator support and redundant HVAC systems, were 100% available throughout Hurricane Rita. Generators and fuel tanks were "topped" off and contracts with fuel carriers were secured. All systems remained on-line throughout the hurricane without interruption.

Communications - CyrusOne initiated its Emergency Management & Response Plan for Hurricane Rita on September 17th, 2005. The Emergency Management & Response Team was immediately mobilized and the plan was activated. Once Hurricane Rita became a threat to the Texas coast, customer disaster recovery plans were reviewed and communication protocols were initiated and operational.

System and Network Management - CyrusOne's Managed Services teams quickly began working with customers on the September 20th to activate procedures to enhance their abilities to maintain 100% system and network availability during the storm. A few of the changes included DNS changes, email re-routing, backup tape logistics, router management changes, etc. The result was that all system and network monitoring and managed customers experienced no downtime as a result of this storm.

"CyrusOne is committed to ensuring the availability, security and integrity of business-critical data and applications 24 hours a day, 7 days a week," said David Ferdman, president & CEO for CyrusOne. "And I'm very pleased with the dedication, professionalism and execution our team demonstrated during the hurricane Rita response."

David Langston, CIO at Houston-based Allied Home Mortgage Capital Corp., who uses CyrusOne's data center services for business continuity, said, "CyrusOne was thoroughly planned for this event. Their expertise and professionalism demonstrated during hurricane Rita made us feel at ease. They did a great job and kept our systems available throughout the storm."

CyrusOne experienced no service interruption to either internal or customer systems. The Emergency Management & Response Plan for Hurricane Rita was executed as planned and operations remained in a "business-as-usual" state for all data center, systems and network management, and remote monitoring customers.
