Surely it is. Just read the information stating what timezone the
computer is located in.
It wouldn't work for me as I am on one side of Canada but I connect to the
Internet on the other side.
There are times that I can get a quicker download from overseas than in North
America.
Your case is an exceptional one that cannot be solved in general by
passive location systems. It is the same problem as 'I'm in Canada but my
proxy server is in Australia' for GeoIP. Pathological cases like that just
cannot be generally solved by passive sytems because it is always possible
to setup a configuration where a person's actual location is unrelated to
their apparent network location.
But for better than 90% of people either GeoIP or using the timezone
locale will produce decent results easily.
A dynamic 'learning' system that measured number of hops/network latency
and adjusted preferred mirrors based on the learned network configuration
could do even better as it learned what mirrors were probably good for a
user and which were usually poor choices.
