KT官方本来是有个免费20Mbps锐速加速的。但是记住,你机器不重装的话,这个免费20Mbps加速可以一直用,只要你机器续费,那免费20Mbps一直可以用。但是不幸的是,你机器重装了。那抱歉,没有免费的20Mbps了。具体可以参考官方邮件回复:
We apologize for inconvenience , Unfortunately, the Krypt Turbo – Free 20 Mbps can only be installed once. But, you have requested to reformat your server via Ticket #9xxx, (Time:8:44:09AM Oct/21/2016), so it was gone and you will have to purchase a new Krypt Turbo.
