I remember that when I first started SEO last year, I posted a bounty on SeoWhy about the IIS log of the website. The general description is: Baidu spider crawls the website, why does the log appear with the 200 0 64 code? What does 64 mean?
We received enthusiastic responses from many people, with roughly the following seven opinions:
1. 64 means 64-bit system;
2. 64 represents the number of crawls;
3. 64 means normal and does not need to be ignored;
4. 64 means that the web page has not been updated;
5. 64 represents the precursor of station k;
6. 64 indicates that the website is in the assessment period;
7. 64 means that the spider failed to compress and decrypt the Gzip website;
Due to the lack of SEO experience in Fuqing and no detailed analysis of the website logs, the matter was left undisturbed. But through some information I searched, I vaguely felt that it was related to the server or network conditions, but I couldn't tell the specific reason.
I discovered this problem again on the A5 forum today, so I downloaded and analyzed the website logs of the flooring company I serve, and felt that it was necessary to correct some wrong views and do scientific SEO.
First, let's analyze the specific meaning of the status code 200 0 64 in the Windows system.
Enter: net helpmsg 64 at the Windows command prompt, press Enter and we see "The specified network name is no longer available." This confirms the point of view of a famous blogger on the Internet: the session is faulty and the request is unreachable. So is it possible that when the spider crawls the server, the server resources are insufficient, causing the request to fail? This Fuqing SEO has reservations.
Then the following example of the floor enterprise website served by Fuqing SEO will be used to parse the log and the phenomenon of 200 0 64 will appear.
1. First of all, the corporate website uses an independent IP server, which is from the Jiangsu Telecom computer room;
2. The author randomly checked the log files for several days and found that the 200 0 64 code appeared almost every day;
3. In the log file, the author found that the 200 0 64 status code appeared when the Baidu spider 123.125.71.12 crawled 2197.html;
4. Run the DNS reverse check command nslookup at the command prompt to confirm that Baidu Spider, the hostname of Baiduspider IP is named in the format of *.baidu.com.
5. Use the same method to determine other log codes that appear 200 0 64, and find that the IP segment where the status code is located is 123.125.71.*
6. Use the ip138 tool to query 123.125.71.* as the IP segment of Beijing Unicom;
Fuqing seo made a bold guess as to the reason for the 200 0 64 status code on this website: the website server analyzed by the author is a telecommunications computer room. When Baidu spider network accesses the telecommunications server through the IP segment, due to problems with the intercommunication between the two networks, the spider cannot obtain the website content normally. Baidu Netcom Spider then gave up crawling the index, so the 200 0 64 status code appeared.
The current competitive situation among domestic network operators is that competition in their respective markets is extremely fierce and frictions continue. The direct result of competition is that on the issue of Internet interconnection, operators artificially limit each other's data exchange speed. Some people joke that the farthest distance in the world is not the distance between me, you and him, but the distance between Telecom and Netcom.
7. The author once again checked some log files and found that the status code 200 0 64 will also appear when Baidu Spider Telecom IP and Telecom IP visitors access the website;
8. Bing spider IPs are all from the United States, and there are also 200 0 64 status codes. Google Spider has not found them yet.
Today, I saw another expert’s analysis on the forum: When Baidu Spider accesses a page, it cannot complete the acceptance of all the data on the page within a specific period of time. In the end, the protocol for accessing the page returns to normal. However, during the process of returning all the data on the page, the server or network The situation at that time led to failure and the 200 0 64 phenomenon occurred.
Also attached is the conclusion of an independent SEO expert: IIS and Apache exist in the server at the same time; IIS often restarts for no reason; server CPU usage is often 100%.
Fuqing SEO once again summarized: When the network request is unreachable, the 200 0 64 status code may appear, whether it is Telecom, China Netcom or China Mobile, so a better approach for domestic users is to use a dual-line host or a three-line host. If the customer base is distributed around the world, it is recommended to use a quality-guaranteed full-network Internet cloud host.
Through this example, Fuqing SEO has some thoughts. There are many people doing SEO, and there are a lot of comments about SEO on the Internet. If you make subjective assumptions that are not based on factual data, it is pseudo-SEO and unscientific. Such remarks are harmful to others and ourselves in a small way, but in a big way they are a hindrance to the development of the SEO industry!
Maybe the author's case analysis is just a case and does not represent the majority opinion, but Fuqing SEO advocates that everyone should do scientific SEO and use data and facts to speak!
