Web Application Monitoring

Leading Open Access Online Publisher of Scientific Literature Selects
Neustar to Further Bolster Performance and Improve Customer Satisfaction

STERLING, VA, February 18, 2009 – Neustar, Inc. (NYSE: NSR) today announced that the Public Library of Science (PLoS) has selected Neustar’s Webmetrics Application Monitoring service to augment the performance capabilities of all PLoS online services, thus ensuring a positive experience for customers.

PLoS is a nonprofit organization committed to making the world’s scientific and medical literature a public resource. All PLoS journals are immediately and freely accessible online. The customer experience when accessing their nine sites must be uniformly positive in order for PLoS to achieve its knowledge-sharing goals.

Neustar’s Webmetrics Application Monitoring service helps PLoS monitor online
resources such as journals, blogs and search capabilities to ensure they are available and functioning properly. As PLoS makes use of innovative new communication tools, monitoring becomes more complex, making the Webmetrics Application Monitoring solution an ideal fit. Monitoring can occur in various intervals – as quickly as every 60 seconds, if necessary. Alerts are sent to PLoS once an issue is identified, so that it can be resolved as quickly as possible before customers are impacted. Further, ongoing reports and analysis are provided to assist PLoS in identifying and defusing potential problems
before they occur.

“Neustar’s Webmetrics Application Monitoring service helps us to deliver on our
mission of providing scientific and medical literature research as an online public
resource,” said Josh Klavir, systems administrator at PLoS. “We use innovative tools to make information easily and freely available on our website. Our customers have to have a great experience every time they visit if we want them to come back, and Neustar’s service helps us achieve this.”

“The Public Library of Science is providing an outstanding service to the scientific
community, and Neustar is pleased to assist them in achieving their goals,” said Alex Berry, senior vice president of Neustar’s Internet and Infrastructure Services Group. “By helping to ensure a positive end user experience, the Webmetrics Application Monitoring service is helping PLoS take advantage of the Web as an innovative and cost-effective tool for information sharing.”
