测试一下：你的ISP对BT下载做限制了吗？
很多ISP（互联网接入服务商）都悄悄地对BT下载做了限制，你想知道你家网络所用的ISP是否是个限制BT下载的“坏家伙”吗？
一个国外网站提供了这样一项服务——在线测试你的ISP是否限制了BT应用。
目前全世界已经有5300多位网友参与了测试并贴出了他们的测试结果（http://broadband.mpi-sws.mpg.de/transparency/results/）。

如果您也参与了测试，请在本文后留言将结果告诉我们（无须注册）。
不过，这个测试很火，测试服务器很忙，我还没能测试成功。估计在中国的中午到下午，西方都是半夜的时候，比较容易测试成功。
