That appears to be a cached report from September 2009. Here's the URL that generates a dynamic report for the period beginning seven days (604,800 seconds) before the moment you request it:
It's interesting to observe the changes over almost three years. The range of the graph is almost three times as large. ".local" bubbles up from #5 to #3 (which makes me think that DNS forwarders ought to just drop ".local"). ".home" came out of nowhere to grab fourth place. The number of requests for ".arpa" has declined -- but why? Brazil has overtaken Russia for the most-requested country TLD. And what is up with that crazy ".belkin" TLD -- zillions of home wireless routers, pinging a thing that doesn't exist?
