According to RFC 7872 measurements (a must read, even if it is about
extension headers, not specifically about fragments), problems occur
mostly at the edge. Lot of good eradings in its references, too.
30.51% of Web servers do not receive fragments. Between 5.08% and
6.78% are before the destination AS.
