VeriSign (VRSN)

Operations Infrastructure

Our operations infrastructure consists of secure data centers in Mountain View, California; Dulles, Virginia; Lacey, Washington; Providence, Rhode Island; Overland Park, Kansas; Melbourne, Australia; London, England; Berlin, Germany; Kawasaki, Japan and Fribourg, Switzerland. We have also recently completed construction of a new data center in New Castle, Delaware. Most of these secure data centers operate on a 24-hour a day, every day basis, supporting our business units and services. Key features of our operations infrastructure include:

As part of our operations infrastructure for our Naming Services business, we operate all authoritative domain name servers that answer domain name lookups for the .com and .net zones, as well as for the other top-level domains for which we are the registry. We also operate two of the thirteen externally visible root zone server addresses, including the “A” root, which is considered to be the authoritative root zone server of the Internet’s domain name system (“DNS”). The domain name servers provide the associated name server and Internet Protocol (“IP”) address for every .com and .net domain name on the Internet and a large number of other top-level domain queries, resulting in an average of over 40 billion responses per day, and peak loads of over 50 billion responses per day, during 2008. These name servers are located around the world, providing local domain name service throughout North America, South America, Europe, and Asia. Each server facility is a controlled and monitored environment, incorporating security and system maintenance features. This network of name servers is one of the cornerstones of the Internet’s DNS infrastructure.

In 2007, VeriSign initiated a large-scale infrastructure upgrade called “Project Titan.” This effort is intended to increase the capacity of domain queries handled by our DNS infrastructure. Project Titan is also designed to further fortify our infrastructure to repel significant distributed denial of service (“DDoS”) attacks and provide enhanced monitoring and logging capabilities. Project Titan is scheduled to be completed by the end of fiscal 2010. As of December 31, 2008, this project is on target for the scheduled completion; all of the U.S. facilities have been upgraded and significant progress has been made in upgrading our European and Asian facilities. As part of Project Titan, we have also deployed more than 40 regional resolution sites throughout the world to support the initiatives of Project Titan in specific locations.

To provide our Communications Services, we operate a SS7 network composed of specialized switches, computers and databases strategically located across the U.S. These elements interconnect our customers and

U.S. telecommunications carriers through leased lines. Our network currently consists of 13 mated pairs of SS7 signal transfer points (“STPs”) that are specialized switches that route SS7 signaling messages, and into which our customers connect. We own nine pairs of STPs and lease capacity on four pairs of STPs from regional providers. Our SS7 network control center, located in Overland Park, Kansas, is staffed 24 hours a day, every day of the year.

Call Centers and Help Desk:    We provide customer support services through our phone-based call centers, email help desks and Web-based self-help systems. Our California call center is staffed 24 hours a day, every day of the year and employs an automated call directory system to support our SSL Certificate Services and IAS businesses. Our Virginia call center is staffed 24 hours a day, every day of the year to support our Naming Services business. Our Washington state call center is staffed from 8:00 a.m. to 5:00 p.m. Pacific Time and employs an automated call directory system to support our Communications Services business. All call centers have a staff of trained customer support agents and provide Web-based support services utilizing customized automatic response systems to provide self-help recommendations.

Operations Support and Monitoring:    Through our network operations centers, we have an extensive monitoring capability that enables us to track the status and performance of our critical database systems and our global resolution systems. Our distributed network operations centers are staffed 24 hours a day, every day of the year.

Disaster Recovery Plans:    We have disaster recovery and business continuity capabilities that are designed to deal with the loss of entire data centers and other facilities. Our Naming Services business maintains dual mirrored data centers that allow rapid failover with no data loss and no loss of function or capacity. Our SSL Certificate Services and IAS businesses are similarly protected by having service capabilities that exist in both of our East and West Coast data center facilities. Our critical data services (including digital certificates, domain name registration, telecommunications services and global resolution) use advanced storage systems that provide data protection through techniques such as mirroring and remote replication.
