Connectivity between different server groups

[Maximus5]

I've noticed a different in Connectivity between 2 different server groups.

 

The ones labeled 'Group 1' I seem to suffer from constant 'random' server disconnects, where as the ones labeled 'Group 6' seem to show a slight lag for the first 5 to 10 minutes after every loading screen.

 

Don't know if its my location or not, but the Group 6 servers seem more stable than  the Group 1 servers!
