Has something changed with GEOIP?

Afternoon all!

I am using maxmind geoip database and as of yesterday any traffic sent to GB goes to my ''other'' landing page when it should be going to my UK one, i havent edited anything or touched it in months as my links all run through prosper, is just happening to me or is other people finding the same problem??

Thanks

Do you use the latest database?

Do you have the IP address that mis-directed?
