It depends on the information available about that IP address. While
addresses are allocated to countries and there are a number of
services which provide that level of granularity, it may not be
possible to match a particular ISP's data to a city. Or Google may
know that the city returned for a particular IP address is wrong -- my
IP address will be listed as London, for example, even though I'm
nowhere near there.

Except that you wrote "I feel confident that I have done something
that has broken it." and presumably your code is getting the client
location and finding it to be null.

If you provided a link to your page, you could have several dozen
people try it from different locations and report back whether it
retrieved their location correctly or not. Or whether in fact you have
indeed broken it.
