另外发现justhost的备份功能不能使用，于是提交了一个ticket给他们，得到答复如下：

Due to your recent server migration to our upgraded servers, a backup has not been generated with the new system. We may be able to get you a backup from the old server, but if possible, I would highly suggest waiting for a backup to be generated in the new system. These can take 3-7 days, but will be able to do a full cPanel restore in case of an accident or problem.

意思是说，备份功能还不能使用，可能还需要3-7天才可以启动。如果你也遇到同样的问题，就不用疑惑了。

Dear ***,

We’re pleased to inform you that we will begin upgrading your account,
and all associated subdomains, to a new hosting server within the next
48 hours.

This upgrade requires that we take your websites offline for a short
period of time to complete the transfer. Anticipated downtime is
between 1-2 hours; to help reduce the visibility of this outage, your
account will be moved during the early morning hours (MST).
Additionally, we will be required to change your website’s IP address;

In order to facilitate the smoothest transition possible, we’ll be
updating your DNS entries automatically during the transfer, and will
make the website accessible at the previous IP address for
approximately one week after the upgrade completes. Should you be
managing your own DNS, (less common) your new IP address will be
provided in a separate email post-upgrade. To provide a seamless
upgrade process, your website will continue to be available at the
previous IP address for approximately one week. However, we suggest
updating your DNS entries immediately to verify proper functionality
for your hosted domain(s).

Please do not hesitate to contact our Support department if you have
any questions about this process.

意思大致说，很高兴的通知您，主机的硬件将会在48小时内升级，将会有1-2个小时的访问中断时间，然后会更换ip地址，以前的ip地址还可以一个星期内继续有效。

过了两天收到了升级成功的通知信：

Dear ***,

The upgrade of your account, and all associated subdomains, to a new
server has completed successfully. Your website(s) are now hosted at
a new location, with the following IP address; please keep this for
your records.

******

If you are managing your own DNS entries for your domains, not common,
please update them now.

Like the previous email mentioned, your website is still available at
the old IP address, and will remain available for approximately one
week.

While no data loss was encountered during the upgrade, we suggest you
browse through all your hosted domain(s) to verify that they are
functioning properly. Additionally, note that this process required a
change in server timezones, from Central Daylight Time (GMT -5) to
Mountain Daylight Time (GMT -6). Any automated tasks you have may
require adjustment to trigger them at the desired intervals.

Lastly, this upgrade included several software upgrades and changes.
The most noteworthy being a new Domain Manager, a new Billing
interface, and the more robust SimpleScripts, which replaces
Fantastico. You can directly import your Fantastico installed
software to SimpleScripts, which will manage the installations and
upgrades as Fantastico did.

If you have any questions about your account post-upgrade, or
experience any trouble at all, please do not hesitate to contact our
Support Department.

虽然不知道升级前后的具体配置，但明显还是感觉网页的反应速度快了很多，希望Justhost性能有更好的提升，做又便宜又可靠的主机，这样我就不用为选什么样的美国主机操心了。

那么HostMonster主机如何开启GZIP压缩呢？

首先，在网站根目录下php5.ini加入以下代码
output_buffering = Off
output_handler =
zlib.output_compression = On
zlib.output_compression_level = 6

其次，在网站根目录下.htaccess加入以下代码
addhandler x-httpd-php5-cgi .php .html .htm .js

需要注意的是，上述代码都是在php5.0以上版本修改的，如果是php5.0以下版本，需要修改的是php.ini文件，以及在.htaccess里面添加的代码是：addhandler x-httpd-php-cgi .php .html .htm .js

Hostgator如何开启gzip压缩功能

cPanel面板中，操作方法如下：
登录cPanel面板，点击“Optimize Websote”(或“优化网站”)选项，在出现的界面中选择“Compress all content”(“压缩所有内容”)，最后，点击“Update Settings”(“更新设置”)即可。

如果大家代码修改成功后，不知道网站是否有效，可以到以下网站检测是否开启了GZIP压缩：

下面就以本站的查询来教大家查看是否支持压缩。我们打开这个网址http://tool.chinaz.com/Gzips/
在出现的网页中，输入自己的网址，就能看到相关的信息了，非常简单。

了解更多关于bluehost介绍

首先，如果要使用Bluehost的免费SSL ，首先要修改网站的链接形势。用户必须把网站的基本链接更改为如下形式：

https://secure.bluehost.com/~username.

其中，username是你的cPanel上的用户名，8个字符，登录cPanel后，可以在BlueHost cPanel的左侧看到。

值得注意的是，共享的SSL证书对数据有限制。为了避免滥用secure.bluehost.com的SSL代理，任何超过100kb 的内嵌数据（图片, 音频等）将被截断，这是针对每个文件，而不是页面的总大小。这样会导致页面可能只会加载一半，特别是对于那些有大图片文件的网页。
当你在通过secure.bluehost.com使用共享SSL证书时，如果遇到网页（或者图片）只能加载一半等这样的情况，可以尝试以下几种解决方式：

• 减少图片的数量；
• 缩小图片的大小；
• 将图片转换成其他压缩比比较高的格式，如.png，.gif等；
• 确认内嵌的数据没有超过100kb
• 如果这些方法都不能解决你出现的问题，那么你可能需要使用一个独立IP和独立的SSL证书。

这样就被扣除了10美元的域名费用.
所以在这里提示大家一下,当你的主机不用了之后,如果域名还希望用的话,可以选择继续使用或者转出,但是如果你这个域名不再用了,那就要注意了,要在域名管理处,一定要择不自动续费,要不然会发生以上这样的事情的.
