Equinix London Slough Data centre open for customers

Equinix Inc. (Nasdaq: EQIX), the leading provider of network-neutral data centres and Internet exchange services, has announced that it has completed the phase 1 build out of its London Slough (LD4) data centre.

The new construction, which was prompted by strong customer and market demand, is now available for new customer deployments. Among the first customers to move into the newly opened site are a leading global financial services firm and one of the world's top five providers of IT services.

The site is the largest of Equinix's four centres in London and Equinix has constructed a purpose-built shell to accommodate two floors of approximately 6,500m2 each. Phase 1 offers 5,000m2 of net data centre space. Phase 2 expansion is due for customer deployment during summer 2008, adding a further 5,000m2 of high specification net space.

The opening of the site, in response to strong customer growth, allows Equinix to expand its capacity in a market where it has operated since 1998: “The opening of the site represents a significant increase in our capacity and allows us to maintain our momentum in this important market,” comments Russell Poole, General Manager - United Kingdom. ”We are able to meet increasing demand from organisations seeking to leverage Equinix's secure and robust colocation facilities, as well as the multitude of carriers offering network services at Equinix."

The new data centre is built using innovative design conventions and features a physical infrastructure that is consistent with Equinix's industry-leading standards for high-performance security, environmental control and power availability. The site provides immediate access to eight network service providers including Abovenet and Exponential-e.
