Operations

London
Operational since 1990, Telehouse North became Europe's first purpose-built neutral colocation facility. LINX traffic has been moving through the carrier-neutral Telehouse campus since its opening. Telehouse hosts the vast majority of internet peering traffic from LINX.

It is the main hub of the Internet in the United Kingdom. In response to growing demand for a Central London location, Telehouse opened an additional colocation facility in 1997, Telehouse Metro, in the London Borough of Islington near Silicon Roundabout.

A second building at the Docklands site, Telehouse East, was opened in 1999 and the construction of a third building, Telehouse West, at its Docklands site was completed in March 2010.  In July 2014 KDDI announced that a fourth building North Two would be built on the site, adjacent to the existing Telehouse North building. In August 2016, Telehouse Europe opened $177 million North Two data center of 24,000 square meters, increasing its capacity at the Docklands site where it already had 73,000 square meters of space. According to Telehouse, North Two is the only UK data center to own a 132 kV on-campus grid substation that is directly connected to the National Grid, reducing transmission losses and improving power density and service continuity. North Two also utilizes the first multi-storey adiabatic cooling system in the world, delivering an industry-leading 1.16 PUE. The site has a capacity of up to 73 MVA in total.

Telehouse London is the primary home of the London Internet Exchange (LINX) since 1994, due to the number of carriers present in the data centre and the level of latency, Telehouse is one of the key Internet hubs in the world.

LINX, Packet Exchange, LONAP and LIPEX are present at Telehouse Docklands.

In 2012, Telehouse built their own primary substation, at 50MVA and two 132kVA power lines directly connected to the high voltage power network for the London Docklands site.

As of March 2019, Telehouse London North is listed as most populated datacenter in EMEA by the data center rankings, working with over 530 network carriers, ISPs and ASPs, including Amazon Web Services, Google Cloud Platform and Microsoft Azure, as well as CenturyLink, Hurricane Electric, Interoute, Voxility, TeliaSonera and NTT communications. Existing Telehouse customers can interconnect to any of these parties via a cross connect.

Paris
Telehouse Europe operates three sites in Paris:
 Telehouse Paris Jeûneurs. Opened in 1996 near the famous Rue du Sentier.
 Telehouse Paris Voltaire which opened in 1998.
 Telehouse Magny-Les-Hameaux (Yvelines département). Originally a national military defence location, the site was converted into a data centre in 2009 and now provides 15,000 square meters of colocation space.

Frankfurt
Telehouse Europe also operates one site in Frankfurt:
 Telehouse Frankfurt. Opened in 2012, Telehouse acquired one of Germany's largest colocation sites, Databurg.
