Basic knowledge of webmasters (below)

The domain name has been registered and resolved for six hours, the space has been activated, and the webpage has been correctly uploaded. Why cannot the website be displayed?

Many administrators are often "acute". After receiving the website communication and getting the FTP account and password, they immediately want to upload and see the website effect that has already been done well. This can usually be achieved, but sometimes the domain name does not have a resolution record locally due to the incomplete refresh of the Telecom DNS, just like a person who does not have a "Account" cannot access or upload webpages.

　　Solution:
The best way is to wait about 4-8 hours for the general Telecom DNS refresh. It takes at least 10-20 hours for normal access from the domain name to the global network.

If you can't wait, you can first complete the upload, debugging, preview, and other work methods:

1. confirm that your domain name has been successfully registered, as long as you find that no matter from which service provider you can not register this domain name;
2. Modify the network attribute of your computer and specify the DNS in the TCP/IP attribute as
3. Windows 98 must be restarted to make the settings take effect.

How to handle network faults?

Network faults are related to telecom service providers, that is, service providers that provide server rooms and hosting services to website service providers. Currently, there are two reliable service providers, China Netcom in the north and China Telecom in the south. If their lines are broken or the network is blocked, the website may be inaccessible. Another possibility is that the local telecom DNS server is faulty or the refresh is not timely, which may cause Website access problems. These problems are beyond the capabilities of the website service provider.

Solution: there is no good solution for telecom faults. Generally, the Service Chamber of Commerce helps you understand the fault resolution situation and provides immediate support and feedback.

Why cannot I upload a file or cannot see the uploaded page after the file is uploaded normally?

Theoretically, this is the case. However, because the computers used as virtual hosts use computers with high performance, a host can support a certain number of virtual hosts. When this quantity is exceeded, users will feel the performance decline. If configured properly and over-high-speed lines are used, the performance of virtual hosts is usually better than that of independent hosts connected by low-speed lines (such as 256 K and 1.544 M. In a competitive environment, we will not increase the number of virtual hosts and sacrifice the interests of users to pursue the ultimate profit. Because in that case, we will lose our "God ".

My webpage is normal locally. Why can't I see any images after uploading?

1. Make sure that the image has been uploaded to the server. 2. The picture inserted during webpage creation should be marked with a relative path.

After the page is uploaded, why is the original default page displayed?

There are two possibilities: 1. The page is not uploaded to the/root directory; 2. The original default page is not deleted or overwritten.
