RackNerd不少人发现racknerd的vps有极高的性价比，而且在网络上面搜索发现口碑也很好，但是不知道买racknerd哪个机房才适合自己，所以想把racknerd的所有机房的IP和测速文件找到一一来实验，确信这样才是最适合自己。为此，本站罗列了racknerd全部数据中心的测试IP和测速文件，方便大家一一测试。需要提示大家的是，如果你将VPS开启BBR的话，那么下载文件的速度可能会有较高幅度的提高，或者直接用第三方xanmod也能达到同样的目的。
建议大家在晚高峰（22点-24点）期间测试，这个时段是国内出口最堵最爆炸的时间段。

SSH登录，复制、粘贴、回车就开启了BBR：
echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf \
&& echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf \
&& sysctl -p && sysctl net.ipv4.tcp_congestion_control
