Telehouse Europe

Telehouse Europe is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Telehouse Europe rather than just read about it. In short: Telehouse is a major carrier-neutral colocation, information and communications technology services provider based in Docklands, London. Established in 1988, it operates in London, Paris and Frankfurt.

Key takeaways

Telehouse Europe belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Telehouse Europe to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Telehouse Europe from memory before moving on to harder problems.

Reference excerpt

Telehouse is a major carrier-neutral colocation, information and communications technology services provider based in Docklands, London. Established in 1988, it operates in London, Paris and Frankfurt. Part of the global Telehouse network of data centres, the brand has more than 45 colocation facilities in more than 20 major cities around the world including Istanbul, Beijing, Shanghai, Hong Kong, Singapore, Vietnam, Tokyo, Toronto, New York and Los Angeles. KDDI, Telehouse's Japanese telecommunications and systems integration parent company, operates data centre facilities in America and Asia.

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, Telehouse Metro later closed in 2020. 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 since 1994, while UK internet exchanges like LONAP are also present. 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.

Worked examples

Example 1 — a first encounter with Telehouse Europe

Start with the simplest possible case. Write down what Telehouse Europe claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Telehouse Europe before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Telehouse Europe ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Telehouse Europe

In research: Telehouse Europe appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Telehouse Europe in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Telehouse Europe is common in secondary-school and first-year university syllabi. It links to neighbouring topics Data centres in the United Kingdom, Infrastructure in London, Internet hosting, so understanding it makes those chapters shorter.
In everyday life: Look for Telehouse Europe outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
