Everybody sets traffic to Do-Not-Fragment. Nobody wants their routers to fragment packets anyway; you might as well ask to get a notification when too big packets are dropped. Nobody wants to have their servers reassemble fragments, it's too much work; many servers just drop any fragments they do get. I ran servers pushing 20 gbps of downloads, and would receive on the order of two fragments per second. It looked legitimate, so I preferred not to disable fragment assembly, but I'd set the reassembly buffer as small as possible; there's no need to keep more than say 16 fragments... if you're getting more than a handful of fragments, it's ddos and that one guy with a weird network will just have to deal. They probably can't use any other sites anyway.
