Raja has also re-written the historical traceroute facility that takes nightly traceroutes and allows one to retrieve and compare them. He then extended it to use the reverse traceroute facility to provide histories for NUST, CERN, UM as well as SLAC. When the UNIMAS and UTM traceroutes work, we can include them.

Its main use at the moment maybe to find roughly the location, i.e. region/country/state, a target is in. This is particularly useful for proxies and for routers (the latter are typically mis-found by GeoIPtools to be in the corporate HQ of the owner (e.g. Berkeley for ESnet routers). It would be really valuable if router owners provided DNS LOC records filled out.
