The Technic server link must be bugged. I clicked it and it brought me to a error page. I fixed it by changing the link to http://mirror.technicpack.net/Technic/servers/tekkitmain/Tekkit_Server_v1.2.6.zip
All I did was take out the "b" In the "v1.2.6b.zip" This may be a early version but its fixed, for me at least.
