HostMonster主机一直以来速度都不错，但是近日来网站的访问速度突然下降了很多，变得很慢。一开始以为是个别站长的问题，但是随着越来越多的用户反映，加之和HostMonster同属一家的BlueHost、JustHost用户也遭遇了同样的困扰，所以我们带着大家的困扰向HostMonster官方咨询查明原因。

不久前发送ticket到官方询问原因（发送ticket内容无关痛痒这里就省略了），然后邮箱很快就收到了回复邮件，感觉很快，一阵大喜，打开一看。相当失望，原来是系统自动发的，只是提醒用户官方已收到邮件，要我们耐心等待。不过好在他们办事效率还是很好的，没过多久就正式收到了官方的回复，要我提供了空间域名和后四位登录密码，我提交后今天收到了他们的回复邮件，具体的邮件原文是：
Hi,
The Chinese Government actively monitors and blocks many different IP addresses, IP ranges, and websites. It seems that your IP address may be blocked by the Chinese Governments firewall which is the most likely reason for the slowness and errors you are experiencing. We do offer you the ability to purchase your own, unique Dedicated IP address for your hosting account.

Purchasing a dedicated IP will also give you these additional perks:

1. It will be your very own, unique IP address for your hosting account.
2. Longer script execution time: 12 hours for HTML, PHP, downloads (up from 10 minutes), twice as much SSH/Shell time, and unlimited time for daemons (up from 10 minutes).
3. TCP/UDP Port Control. Some services your site may need require custom ports to be open for connections; without a Dedicated IP these ports cannot be opened on your account.
4. No longer necessary to include the @domain.com part in FTP logins.

Its available for just $30/year and can be purchased from the Dedicated IP tab at the top of the cPanel.

从他们的回复中看，HostMonster主机访问慢最可能的原因是：由于一些IP地址或地址段受到国内防火墙的阻止或限制导致的。官方给出的建议是：用户可以购买独立IP来尝试解决这样的问题。
