贵阳电信流量劫持网络，向用户强推广告 / 四六文摘

我使用的是贵阳电信的ADSL，最近一段时间在浏览网页的时候总是会弹出一些它们的广告。这种情况以前也出现过，不过不太频繁，忍忍也就过了。可能是看到用户太善良了，又很好糊弄，最近变本加利，有时每隔几分钟就来一个，已经严重影响到了我的阅读。据我所知，一些提供免费空间的网站也经常会在其用户的网页内插入一些广告，这无可厚非，毕竟是免费的嘛。可是我还没看见哪一家空间商给付费用户的网页也插入广告，如果有，可能也活不了多久了。

作为一家电信运营商，贵阳电信的这种作法是不地道的，是一种侵害用户利益的行为。作为付费用户，贵阳电信运营商却把我们这些付费用户当免费用户看待，在没有任何通知的情况下擅自在用户浏览网页插入广告。说得不客气一点，这是一种违法行为，必须立即停止这种侵权行为。

IIS7网站监控可以及时防控网站风险，快速准确监控网站是否遭到各种劫持攻击，网站在全国是否能正常打开（查看域名是否被墙），精准的DNS污染检测，具备网站打开速度检测功能，第一时间知道网站是否被黑、被入侵、被改标题、被挂黑链。精益求精的产品，缺陷为零数据提供！
它可以做到以下功能：

1、检测网站是否被黑

2、检测网站是否被劫持

3、检测域名是否被墙

4、检测DNS是否被污染

5、网站真实的完全打开时间（独家）

6、拥有独立监控后台，24小时定时监控域名
