Your m247 servers are great. With one exception. Sweden.
My suggestion is to add more swedish servers that are not m247 or switch some to Altushost.
The four Altushost ones work great.
I'm often getting only a couple of mbit/s from the m247 servers while getting 100s of megabits from the four Altushost servers.
It does seem like I'm not the only one to notice that the m247 ones somehow suck. There are about 5x more people connected to the Altushost servers than the m247 servers
Lupus, Norma, Ain and Capricornus pretty much always have 100-150+ people connected.
And then of course they get more than their share of the heavy load/traffic.
Compare this to the m247 ones. They have 15-30 people connected at any time.
I realized after writing this and connecting to some of the other servers that the slower ones are not m247 company, but Kustbandet
