About the Geoindex http://dx.doi.org/10.5259/ukwa.ds.2/geo/1
The ~2.5 billion 200 OK responses in the JISC UK Web Domain Dataset (1996-2010) dataset have been scanned for geographic references - specifically postcodes. This set of postcode citations, found at particular URLs, crawled at particular times, forms an historical geoindex of the UK web. For more details about how the data was created, its format, and how to use it, see here.
The geoindex is composed of some 700,641,549 lines of TSV data, each asserting that a given web page, crawled at a given data, contained one or more references to a given postcode.
