Maxmind www.maxmind.com is a fairly good indicator of what geo-locators are
seeing, but I recall a recent thread here that there have been disagreements
between the various geolocation services.
I think that some of it depends on the reference sources i.e. how many and
what the algorithms are and also the update frequency. Using plain old whois
data, for example, is notoriously unreliable, but definitely "usable" as a
reference.
Might be nice if search engines and cdn's had a verification site for
checking and suggesting corrections i.e.
www.favoritesearchengine.com/ipverifiy
Best,
Martin
