The London Stock Exchange is delighted to welcome TelecityGroup to the Main Market.

TelecityGroup is a pan-European operator of network independent data centres offering a range of highly flexible, scalable data centre and related managed services to a wide range of organisations. By providing its customers with a highly-connected, secure environment in which to locate their equipment, the Group’s data centres act as content and connectivity hubs facilitating the storage, sharing and distribution of data, content and media.
A data centre or ‘‘colocation centre’’ is a facility to house mission critical computer systems and associated components. Data centres house networking and computing equipment such as servers, routers and fibre optic transmission gear, allowing businesses that own this equipment to connect and interact with each other and the internet. This equipment is highly sensitive to environmental conditions and therefore factors such as temperature and humidity are tightly controlled through the use of specialised heating, ventilation and air conditioning equipment. Given the critical importance of these functions to businesses, equipment security and continuous operations are vital and are achieved through the use of redundant/backup power infrastructure, reinforced floors and security and monitoring systems.
