Hi,
I noticed that some pagecounts data files are missing, namely the files in the interval (20090921160000 - 20091001000000) (ends excluded).
See http://dumps.wikimedia.org/other/pagecounts-raw/2009/2009-09/
Does anybody know the reason why these data are missing?
I don't, but you can find themon IA thanks to Lars: https://archive.org/details/wikipedia_visitor_stats_200909
