1&1 to transform disused Hanau nuclear plant into green European data centre

- New data centre in former nuclear fuel facility with space for 100,000 servers

1&1 Internet Ltd., the world’s largest web host by known servers, today announced plans to build one of Europe’s largest data centres in Hanau, Germany. Within a never-used former nuclear fuel facility called ‘New MOX’, 1&1 will build a European data centre providing space for up to 100,000 servers across an area of 10,000 square metres. Like all 1&1 data centres, the new facility in Hanau will use electricity only from renewable energy sources. 1&1 also plans to create around 20 new jobs there, and many more at the company’s R&D facilities in Karlsruhe, Germany.

“The new data centre in Hanau will further optimise the operational efficiency of our Internet services,” said Oliver Mauss, CEO of 1&1 Internet Ltd. “The geographical distance from our existing European data centres is an important aspect of our business continuity strategy, and the new facility will further bolster our pan European backbone” adds Mauss.

1&1’s latest European data centre is scheduled to become operational towards the end of 2009. Primarily, it will host dedicated server services. 1&1 currently operates more than 55,000 energy-saving servers, running mostly on a Linux operating system, that have all been specifically designed for its requirements. The new data centre will also provide capacity for new services such as Software-as-a-Service or Cloud Computing. With these technologies, applications and hardware are moved from a user’s desktop into Internet data centres such as 1&1’s.

“Telecommunication perfectly fits the high-tech location of Hanau,” says Hanau’s Mayor Claus Kaminsky. “Hence, we are very glad that 1&1, one of the world’s largest providers, has opted for our city. A very positive aspect is that finally a very reasonable use has been found for these highly specialized buildings.”

The facility was constructed in the late 1980s, and was originally intended to produce mixed oxide rods made from enriched Uranium and Plutonium. The facility never became operational and by the end of 1995, its former owner Siemens AG decided to give up the facility. Two years ago, the premises in Hanau were finally released from nuclear control legislation - a major prerequisite for 1&1’s involvement.

“Of course, it is a very pleasing side-effect that a formerly contentious nuclear plant is now being transformed into a green data centre,” said Mauss. “Whilst Internet servers require electrical power, 1&1 only uses renewal energy. We also pay much attention to saving energy – after all, the power bill is one of the largest parts of our operational expenses for such data centres. The buildings and the surrounding area provide sufficient space to install energy-saving coolers that use the outside temperature for cooling and thus significantly reduce power consumption. 1&1 also uses low-energy components within all its servers”, he added.

1&1 Internet, the world’s largest web host by known servers, is well placed to provide a high quality service, offering industry-leading connectivity via its own pan-European backbone. 1&1 currently holds 7.7 million customer contracts worldwide and manages over 10 million domain names.
