Last in the domain name and Baidu weight of the practice report this article mentioned the April 23 of my server maintenance stopped service day on several sites, but the impact of these effects in the next day, and immediately after the 28th server was DDoS attack, stop service for about 3 hours, The impact is much more severe than the first stop of 24 hours. May be a continuous server unstable operation caused by the superposition penalty.

The author has been observing the situation of these sites, the following detailed explanation of the two consecutive stop service, the different impact on different sites. Here only to do the situation and simple analysis, for everyone to think about the analysis, do not dare to do what conclusions.

First of all, I would like to talk about my site on the server:

The first echelon, Pr>=3 contains more than 2000 of the old station snapshots within 1st

The second echelon, Pr>=1 included more than 500 of the new station built station more than 3 months, snapshots within 1st

The third echelon, Pr>=0 contains more than 100 of the new station built station 2 months or so snapshot within 7th

Fourth echelon, pr>=0 not included in the new station

Basically according to the snapshot date classification, which PR4 by K's TV show station Vod.lovedsj.com also was zoned in the third Echelon

Because I was only recently began to build a large-scale station, so the first Echelon only 3 sites, Www.dangshan.info and Bbs.dangshan.info and http://soubq.com

The first stop service was because yesterday's security team maintained the server, redo the system and rerun the station, careful and careful to do security work, resulting in all 11518.html "> site shutdown 24 hours." The second day after the resumption of the first Echelon site response most strongly! Their snapshots fell from 1st to 10 days ago.

The second echelon of the station, the most snapshots did not update, and did not regress. Instead of the third echelon of the www.bite8.cn, etc. because the update is not a week away from the snapshot of the station, unexpectedly in this day have reached the snapshot within 1st.

The next day, the first echelon of the snapshot was restored. According to the author estimates, this situation should be Baidu to deal with WJ a means. Because of a longer operating time, the site has a higher weight, if suddenly closed, there is a great possibility that the site has sensitive content is WJ shut down. But because Baidu snapshots update frequently, even if these sites are shut down, Baidu snapshots may still retain the information, so Baidu in order not to hot upper body, for a slightly weighted station, as long as the shutdown, Baidu immediately overreact: Snapshot date ahead of 10th, avoid the sensitive content that may appear. And some weight not high website stop service is also normal, no fuss.

The second stop service, is 4 days after the 28th, woke up in the morning found that the site can not be visited, the Admin5 security team to quickly respond, try to log on to the server, from the flow monitoring to see, upload peak unexpectedly to the 30m!! Was DDoS. After treatment, the attack lasted 3 hours. This time can not see the impact on the site. By the 3 o'clock in the afternoon of the day, serious consequences arose.

Www.dangshan.info snapshots of the first echelon retreated to 2003!!! This domain name is only 2 years old. It lasted for a week and has not been answered so far. One of the soubq.com of this weight slightly more small point, was plucked 500, the snapshot date stay at number 27th.

The second echelon of the site is mostly entertainment class, snapshots all stopped at number 27th, where the second echelon of the only PR2 www.qqying.com snapshot back to 21st, the first sink, www.ds557.com snapshot fell to 22nd, these have not yet recovered. But a week later, the second echelon of the only class industry station www.dimchat.cn Snapshot restored to 3rd

The third echelon of the impact of the smallest, but there are gains, such as just mentioned www.bite8.cn, from the snapshot more than 1 weeks, rose to the 3rd, or even a number of repeated K PR4 TV station vod.lovedsj.com, in this day included the home page, and keep a snapshot within 2 days.

Included in the 1-page new station www.gubaiu.cn is 9th to do the Valley Hundred Excellent entry station, also included 100 pages, snapshots never updated to 5th.

Unlike other stations is www.52huaban.com this station 2 months not updated content, this snapshot also to 3 days ... Www.52link.net and www.ndhlg.cn These two stations are added

So the third echelon of this blessing in disguise, the biggest harvest.

Fourth echelon, in this week included 2 stations, including the last article mentioned www.sdwawa.org, this org site did two months, finally included. Because the collection belongs to the normal situation, do not see the actual impact of the other stations to build a new station: how entrepreneurial nets www.ruhechuangye.com and www.dianpingw.cn this week is not included in the normal, so the fourth Echelon does not do evaluation.

This time there is another station encountered special circumstances, www.cxy5.com This station's domain name expires May 1, resulting in a continuous 3rd stop service. Station directly by K. But get rid of www. http://cxy5.com This main domain name is not k, there are more than 100 included, perhaps this with the WWW and without the weight of the WWW difference?? Has now recovered, but a few days can be reproduced, still observing.

has been hanging a single page of the www.dimad.cn in this period of revision, originally included a page was K, waiting to be included in the

21st number of Forums to change the site of the www.lovedtt.com, the original content was K, only the home page, the snapshot is the revision of the day 21st

To sum up briefly, the simple saying is: The higher the weight of the station, the more lethal impact, the lower the weight of the station, the smaller the impact, but it is likely to arouse the attention of spiders, make a response, the collection of the K, the lifting weight of the lifting weight.
