求解论坛搜索功能

1、论坛的搜索功能是不是有问题？每次都返回错误：
This Page Cannot Be Displayed

---

The system cannot communicate with the external server ( search.sgchinese.net ). The Internet server may be busy, may be permanently down, or may be unreachable because of network problems.

Please check the spelling of the Internet address entered. If it is correct, try this request later.

If you have questions, or feel this is an error, please contact your corporate network administrator and provide the codes shown below.

Notification codes:

(1, GATEWAY_TIMEOUT, search.sgchinese.net)

2、另外论坛的站内消息群发功能似乎也有问题。直接用逗号分割的ID列表不能识别，无法发送。

3、另外可不可以建议斑竹的每天群发上限调高一点点，现在是25？
