Interoute Deploys 60 Gigabits of Connectivity on Its Infinera Network in 48 Hours

SUNNYVALE, CA--(Marketwire - November 25, 2008) - Interoute leveraged its Infinera (NASDAQ: INFN) Digital Optical Network to provide 60 Gigabits/second (Gb/s) of connectivity on a 1200 kilometer route in Europe in just 48 hours, helping a major customer that was experiencing rapid quality degradation on its previous optical network.

In this case, one of Interoute's large global customers had acquired another telecom operator which already owned a large international optical network. After the acquisition, the unprecedented daily volume of data and IP traffic now utilizing the route highlighted the fact that this network was in need of immediate and substantial upgrade. Customers were already beginning to experience quality of service issues.

Interoute operates an Infinera optical network across that same route. The customer asked Interoute if it could provide 60 Gb/s of connectivity, enough capacity to carry traffic approximately equivalent to 7.5 million simultaneous mobile phone calls. Interoute staff worked with urgency to meet this customer request and in just 48 hours the full 60 Gb/s of new services were up and running. Most of this time was consumed in providing the additional connectivity from the customer's network to Interoute's Infinera network. The Infinera modules required for the additional capacity arrived at the sites in a matter of hours, and the Infinera system took just minutes to bring up the capacity, test it to confirm it was running error-free, and begin carrying customer traffic.

This is just the latest among a number of difficult connectivity crises that Interoute has been able to solve successfully for its customers. Interoute CEO Gareth Williams said that the speed of service delivery and the reliability of Interoute's Digital Optical Network has played an important role in helping Interoute become one of Europe's fastest growing telecom operators, with an outstanding reputation for service and quality. "Managing to activate 60 Gb/s of bandwidth in less than 48 hours has made us extremely proud and emphasized again the first-rate quality of our network, and especially our Infinera optical network, as well as the total dedication of our people," said Mr. Williams.

"We are delighted to be helping Interoute as it sets new standards for quality and service in the European telecom industry."
