are there issues with using the data from the IA?

Hi, I am working on the pagecounts data for a project and I have noticed that data for the period September, 21st - September 30th, 2009 are missing.[1] However I also found that some data for that period are avialable from The Internet Archive[2]. I see also that somehow at https://stats.grok.se there are some data available (see for example the page view data for"Influenza" on en.wiki[3]). So, my question is: are there issues with using the data from the IA? I checked that besides for a difference for the file pagecounts-20090921-160000.gz which seems incomplete on dumps.wikimedia.org the rest of the files are the same. Thanks in advance for your help.
