I only want to say thanks to the support!
Yesterday, suddenly i wasnt able to login to my vps. I'm tried all configs, asked in irc at the #centos channel; everybody said i have to reinstall the OS, because the bug is too tiny to find it.
But the Support helped me after a few hours, found the bug and now it's working without any failure!
You want to know, how expensive the personal service was?
It's unbelievable... it costs nothing!
So if u want to buy a servert, do it here. The Support is awesome!
