Intermediary transaction SEO diagnosis Taobao guest Cloud host technology Hall

Recently, from the QQ Group, micro-Bo and other channels to see someone in the "use of the United States and Orange Internet Virtual host site by K", "Web site in the United States and orange Internet large area appears to fall", "the United States orange Internet DNS shielding Baidu spiders crawl" and so on. Talk from "Victims" to the fan-fuelled "vendor machine", "Sell DNS", not lively. Just a period of time before the stupid birds on the site of the U.S. Orange to do a monitoring, but also to talk about "the United States orange Internet K-Station door."

First, the United States Orange K station Door incident

The beginning is in micro-Bo see a netizen posted message, the effect is: The site was K, after the search is IDC in the DNS server detection automatic defense, mistakenly Baidu Spider IP as a malicious IP segment shielding cause spiders can not crawl site. and IDC service provider Mei Orange interconnection only sent an apology letter ended, did not mention compensation.

Then, Lou blog post "IDC mistakenly shielded Baidu Spider led to the site by K", A5 Webmaster Network has user contributors "not afraid of the same opponents of the United States Orange K Station Door review", and so many people understand this information. Next, is the angry webmaster will be the site of the problem directed at the U.S. Orange, all kinds of IDC and DNS service providers also take advantage of marketing.

Second, IDC and the website by K

SEO in the site, the stability of the site access is a very important part of the server or DNS instability is easy to cause the site by K. Stupid Bird Blog has also been due to IDC service provider Huaxia name network problems lead to K station, see "Baidu home is K ten reasons to guess and solution."

Why DNS or server instability will cause the site to be included down or even K station?

First, we should make it clear that the site is a Dynamic data collection. Search engine in the crawl page will be in a certain period of time (depending on the weight of the site, the weight of a short period) on the page to detect, if the test did not find the page will be in the index to delete it, this situation Baidu called it the crawl anomaly.

In the Baidu Webmaster Bulletin for the crawl exception has the following description: "For a large number of content can not crawl the site, the search engine will think that the site has a user experience defects, and reduce the evaluation of the site, in the crawl, index, weight will be a certain degree of negative impact, and ultimately affect the site from Baidu to obtain traffic. ”

From this can be seen, if Baidu spider crawl abnormal Baidu will identify user access will also appear the same situation, and in the "2013,seo How to do?" We have said that the search engine attaches great importance to the user's search experience, then, for users to visit when there is no page that hurt the user experience of the situation search engine will certainly not allow to happen. This will reduce the crawl of the exception page ranking or directly delete the index, and when the site has a large number of this situation, the search engine is likely to be the whole station to delete, that is, we speak of K station. Now you know why a stable host is important, right?

Why is there a DNS quarantine search engine spider phenomenon?

Like "The United States Orange K station door" in this situation is very common, the server's operation and maintenance department neglected spider crawl, easy to Spider's crawling behavior as a similar DDoS network attacks, thus shielding.

How do I know if a problem with DNS or server stability caused the site to be included by K?

Due to IDC caused by the site is down the right behavior we have a variety of methods can be found, such as through the site log, we can see the stability of the server and search engine spiders visit the situation, long-term observation once there are anomalies we are very easy to find problems. In addition, a third-party monitoring tool can also be used to learn about the stability of the site.

And the most common, easiest way is through the Baidu Crawl Anomaly Detection Tool detection site crawl anomaly. Common crawl exceptions such as: 404 pages, IP ban, UA ban and abnormal redirection. Among them, the IP ban is the "United States Orange K station Door" in the error, in the setting of the IP section ban when the error will be Baidu Spider shielding in the case of Baidu is that the site is unable to access the situation caused by deletion or K station.

On the occurrence of this unexpected page crawl accident, Baidu to webmaster warnings as follows: "This is very dangerous!" If the occurrence of the crawl is not resolved in a timely manner, not only your site will bring loss of traffic, the serious situation of spiders may also reduce the evaluation of your site, in the crawl, index, ranking may be a certain degree of negative impact. "Where the site evaluation is the weight of the site, crawl, indexed for the site, and ranking nature is the site rankings."

What happens to Web site falls due to DNS or server instability?

In general, Web site impacts due to DNS or server instability are gradually restored after the problem is resolved. However, if the page is deleted, the index will certainly be affected. This loss is generally the loss of the age of the page, the typical performance of the page snapshot of the bulk update. Here, some sites in the K station after the disallow search engine spider, after a period of time again open, and then there will be included. This method seems reasonable, but do not know after the problem may still exist, there will be the risk of K station. Moreover, the pages accumulated before the age of the page completely disappeared, this is the act of loss.

For the "United States Orange K Station" in the spread of the site, because of the spider shield caused by the site will be in the shield after the release of the gradual recovery, the impact will not be too big. Intentionally to attract Baidu spider, update the original spider like content, and then after a "study period" can be restored to normal, the study period long short-sighted site weight and update content.

Third, the United States and Orange Internet and Huaxia name network IDC comparison

1, the domestic IDC situation and future development

The first reaction was not to be angry at their low-level mistakes, but to appreciate the attitude of the fools to admit their mistakes. With a number of IDC webmaster know that very few service providers are willing to admit that they are wrong, less to see that there are dare to make mistakes published. The small IDC service provider is not reliable at all, but the technology of the big service provider likes to prevarication responsibility, the negative solves the problem.

U.S. Orange is the top ten domestic IDC service providers, there is such a thing we can think of the current domestic other IDC is how a situation, including million nets, new nets, these well-known service providers are not even as good as the U.S. Orange Services and server quality.

The occurrence of the road to create "Orange K Station Door" incident, in fact, stupid bird very heartache. Because this is likely to mean that the domestic IDC in the future will be more dark, this time will certainly let us orange and other domestic IDC long experience, will not send any notice to admit wrong. In everyone is happy to attack the U.S. orange will think, if from then on, all the host business problems even after the announcement is not it?

Accusations can be, but too much aggression may not be a good thing.

2, the Chinese name Net, the Western Digital and the United States orange Interconnection comparison

When you see the announcement of the United States orange, stupid birds very feeling, if the Chinese name network can have the United States Orange Internet dare to admit mistakes and correct attitude is good! Dare to admit mistakes such as Huaxia network such garbage host does not recognize the error, do not solve the problem is much better, this is a customer responsibility problem.

Stupid bird Personal, friends and companies have used million nets, new nets, the Western Digital, Huaxia Network and the United States Orange and other host, and the site has been monitored, from an objective point of view to simply talk about experience.

From the performance of the server, million network because of the price of the performance is the best, followed by the United States and orange Internet and the new network, is the Western Digital, the worst is the Chinese name network. Million network server to calculate the average speed of 165 milliseconds or so, the U.S. Orange and the new network common server speeds in 380 milliseconds, the Western Digital medium host speed in 600 to 1000 milliseconds, while Huaxia network medium host speed in the 700 to 1100 milliseconds.

From the stability of the server, million nets the best, followed by the United States Orange and new network, is again the Western Digital, the worst or Huaxia name network. Million network almost no server downtime, American orange interconnection and new network also less access, the West digital average one months will have one or two times, but each time not more than half an hour, and Huaxia network average monthly 5 times downtime, the longest or even nearly 2 hours inaccessible.

In terms of server bandwidth, many server price differences are also mainly here. The higher the price, the greater the bandwidth, the faster the speed. Under normal circumstances, 800 to 10,000 of the host, million net, new network and the West digital difference is not big. And the United States Orange interconnect even the relatively low price of the host, its speed will not be three times times slower than the high price. And the Chinese name net is not the same, the difference is very outrageous, even if more than 800 host is also million nets and so on 10 times times, compared to the common orange host still three times times slower. However, because the overall bandwidth is higher even if the worst does not affect the speed too much, therefore, this one in addition to the Chinese name net other all go.

From the DNS resolution speed, million nets the best, followed by the United States Orange Interconnection, is the Huaxia name network, the worst is the Western Digital. Million nets generally in 40 milliseconds or so, the United States orange in 100 milliseconds or so, Huaxia network in the 150th millisecond or so, while the Western Digital in 200 milliseconds or so.

From the server panel function, million nets, new nets, the Western Digital better, Huaxia network second, the United States Orange interconnect poor. For example, the common 301 features, 404 features such as the United States and Orange did not.

From the customer service and technical attitude, the Western Digital and the United States Orange interconnect better, million nets, a new network second, the worst Chinese name network. Huaxia Name Network customer service preparation should be the salesman, the server asked them questions, they do not understand, will push you to technology, let you submit work orders. Submitted a work order after the technician is not necessarily when the time to give you a reply, more exasperating is that the general technology can not solve the problem, out of the blame to the customer.

In summary, from the overall, excluding million nets, new nets these high prices. In the United States and Orange Internet, the Western Digital and Chinese name Nets, the United States orange should be considered the best, the Western Digital general, the Chinese name net is rubbish, about the stupid bird in Huaxia network experience can be seen "I in the Chinese name Network encounter."

DNS and server

In this interrupt, some of the QQ group to sell space to use the "United States Orange K station door" to attack the U.S. Orange server is bad, really do not see, DNS is the domain name resolution, and the server is to put the Web site files. DNS is wrong how to infer that the server is poor? To persuade you to need the host, buy a big brand, like this QQ group of small host business don't buy.

On the whole, the domestic IDC service is very poor, I hope you see such irresponsible host will be published, to other people more reference, see those who only to make money regardless of webmaster interests host business. If you have a similar experience, you may leave a message to the stupid bird.
