When applied to a proxy environment (which is my field) it's very
common, as you then have a very high level of concurrency from very many
users. Partially aborted requests is a fairly high percentage of all

Which if this was a proxy may be many orders of magnitude more bandwidth
than the download used while it was being forwarded to a client..
