We have now updated our Historic Index with data for start of August 2013. Here are the new stats:
Historic Index â€“
Unique Pages crawled: 543,749,939,589
Unique URLs: 2,116,030,214,824
Date range: 09 Jan 2008 to 10 Aug 2013
We do apologise for the delay in releasing this update – it was due to growth in unique crawled pages that was getting close to our internal limit of 549,755,813,888 – we have now increased the limit considerably to 140,737,488,355,328!
