Construction of Global Switch's Sydney2 data centre could begin before the end of 2009 with expectations that the current facility's floor space will be 'full' by the year end. Planning for the new centre, to be situated behind the current one in Pyrmont on the edge of the city's Central Business District, is already underway. The company is approaching the build as an extension of the original facility, which itself is nearing completion of the final stages of fit-out and a power and cooling upgrade.
