美国的服务器安装不了linux

[root@ateliere ~]# yum install -y wget && wget -O install.sh http://download.bt.cn/install/install.sh && sh install.sh
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
YumRepo Error: All mirror URLs are not using ftp, http or file.
Eg. </html>/
removing mirrorlist with no valid mirrors: /var/cache/yum/x86_64/6/vz-base/mirrorlist.txt
Error: Cannot find a valid baseurl for repo: vz-base

请问，现在是不是到美国的线路有问题，暂无法在线安装？

ping一下宝塔官网地址看一下，能不能ping通
