Each network has it's own DNS pool. This is where the numeric IP addresses are stored in reference to the named addresses.
Trying different servers on the same network will still go to the same DNS pool. If this is happening on one server on the GalaxyNet network, then it'll happen on all of them.
You should try a different network (eg: EfNet, DalNet, PleasureNet, Xeromem) or any one of hundreds, or possibly thousands of others.
If you get the same thing on a lot of different networks, then it sounds like there might be a problem at your end.
