If you are interested in this kind of data, it's worth noting that there are some older, but, in a sense, more manageable datasets at the Internet Traffic Archive [1]---the data there can be downloaded and does not require being physically shipping through the post.

The largest dataset consists of 1.3 billion requests (for the 1998 World Cup website).

From a research standpoint this data set is much less interesting than a bunch of students/faculty/bots/apps clicking and surfing their way around the whole Internets.
