In May 2012, the the Godaddy main station from China resolution is very unstable, parsing is masked normal, Railway line, basic telecommunications masked more and more GoDaddy DNS server regional interference can notthis Godaddy own domain name can not be resolved, the large number of sites can not be accessed, especially in Godaddy registered domain name owners.

Beginning in July last year, some of the telecom operators in China began to shield part Godaddy's DNS service, leading to large-scale use Godaddy DNS website can not be accessed from China, such a direct shielding NS (DNS) service approach, a very bad influence one or two so-called "harmful information" in order to "punish" a direct result of the thousands of innocent sites can not be accessed, can be described as "rather kill a thousand, can not let go of a" less extreme means.

Godaddy is the world's largest domain name registrar, Godaddy domain name registration fee is very low in the same industry, the average price is only half of the domestic domain name service, is a very good domain name service provider, for example, the year of 139 million net registered com domain name yuan, Godaddy minimum is only $ 50. Many site owners are using Godaddy Domain Name Service. Network service providers of this well-known domain registrar illegal shielding alleged unfair competition. Godaddy accounted for nearly 32% of global market, with other causes of shielding domestic, overseas Sancheng website in the country can not be normal visit.

Any use of the GoDaddy DNS server, there may be the wall. Fortunately, only DNS shield, can be switched from Godaddy to DNSPod host unknown during a few minutes. Domestic DNS manner.

Other normal access to modify the local DNS, try Google dns: 8.8.8.8.

Baidu officially recognized as a plain text link URL Baidu crawl, network of Baidu reptiles be plain text on the link to crawl from Baidu owners club Lee Reply!

1 text link url address, Baidu will find he is a url address and crawl up this address to the url address.

2, whether the link should be passed weights only criteria: whether the user or other sites in this link really recommend your site to this recommendation, whether Users valuable.

Note: plain text link that is to remove the hyperlink URL majority Contributions will be removed hyperlink, which is undoubtedly good news, but can not confirm whether passing weight.

Recently, Baidu large-scale upgrade of the algorithm and revision, engage in panic. First, the failure of Baidu news search, Baidu search engine, frequent errors, especially slightly longer text each will wrong. Which one is clicking on the class of the more popular software algorithm adjustments at running events from the most recent such software provider, can say with certainty that the clicker market. Baidu click software popular in the country, starting in 2009, also known as analog click, P2P technology and agent technology to the realistic simulation of user click behavior to affect search engine rankings. Baidu Union ad interaction point Union, cross-point group and so the nature of the mutual click advertising on Baidu Union conduct penalty.

I also received the e-mail notification of Baidu Union, all Baidu Union websites, Reward Report, click visible human use software simulation behavior has touched the fundamental interests of Baidu, Baidu, of course, can not be tolerated.

User feedback: it took 598 to buy a one-click software originally ranked 15 words, click afternoon clicker analog results gone the next day, not only the word ranking, the most angry, the other keywords ranking disappeared, and worked hard to optimize the site for six months, just search the title search, the company commander Suffix not search.

Sohu IT, said sources from the investment community, Baidu is accelerating capital negotiations with gifted as (UCweb), to controlling or strategic investment UCweb. "Investment in Jinshan, UCweb series of negotiations are conducted by Li himself with people is expected to be reached soon." In June 2012, there had been Baidu $ 400 million acquisition of UC49% stake. But the transaction has not been reached.

 

Baidu internal sources said, Baidu recently stepped up investment in all defense and mobile end, and to accelerate the process of investment, but the investment and M & A, by Robin Li personally intervene.

"Baidu lack of moving side entrance, holding UCweb is the best choice." Analysts said the investment community. Internet analysts had the Keso also said, "If this message (Baidu acquisitions UCweb) is confirmed, it will be Baidu defensive acquisition, the main purpose is to prevent the UC acquisition of other Internet giants."

However, Baidu transactions acquisitions UCweb ability to achieve and there are many factors in the left and right. The source said that contact in June last year, Baidu valuation of $ 816 million to UCweb the UCweb aspects of their own valuation of 10 billion dollars, the final price of the two sides did not  agree. The valuation of UCweb may be higher, Baidu need to pay more cash, Baidu can accept is a problem. Meanwhile, UCweb the founding team as well as Alibaba, Nokia and other strategic investors is whether they can accept a Baidu acquisition is also variable.

As of press time, Baidu and UCweb, not yet to comment on the two sides to discuss the issue.

One way of Thai embarrassed embarrassed at the end of 2012 under the bed to the Chinese film box office record, but also refresh the record. But in IT, data center security failure events erupt frequently, also the impact of enterprise user's psychological line of defense in a meeting. Only look, the security problems of the data center, don't be embarrassed again. "Tai embarrassed".
Cloud computing service is touted to be the IT saints in this era, all services can be "cloud". However, when many companies to be the first to eat crab, but found that often the most vulnerable is their. In recent years, emerge in an endless stream of cloud services broken network events, so that the industry could appall.

People gradually return to the ideal, to more clearly see the true face of cloud computing. It can be said, no matter how lofty dream or to find a secure foothold, cloud services eventually from one data center to be transmitted to a data center, and in the process still could not escape the need, computer, network, power, storage, etc. between collaborative work. As a result, the entire process error and loopholes in the offing, coupled with natural disasters. So, enabled cloud services, you must have a certain amount of mental preparation, but also with a second-hand solutions to deal with.

Editor here, look at the reasons behind a series of broken network events that occurred in recent years. Between from 2009 to 2012. Perhaps make you see: even if the computer error seems inevitable, reinsurance measures seem only security event control in a small probability range.

The off network types: system failure

Typical event 1: Amazon AWS Christmas Eve off network

The cause of the malfunction: Elastic Load Balancing service failure

December 24, 2012, Christmas Eve just past, Amazon did not let their customers have had peace.

Typical event: Shengda Yun stored off network

The fault reasons: data center physical server disk is damaged

August 6, 2012 8:10 pm Shengda Yun due to cloud host failure caused by the loss of user data events public statement published on its official microblogging. The statement said: August 6, Shengda Yun data center in Wuxi, because a single physical server disk is damaged, resulting in the loss of individual users' data. Shengda Yun has to make every effort to assist the user to recover data.

Lead to individual users' data lost because of a physical server disk is damaged, Shengda Yun technicians are given their own interpretation: the virtual machine's disk, there are two modes of production, a direct host the physical disk. This case, if the host's physical disk fails, the cloud host will inevitably result in the loss of data, which is generated by the incident reasons; another is to use remote storage is grand hard disk products, this way the actual is to save the user's data to a remote cluster, and at the same time do multiple backups, and even host a failure will not affect a the Cloud host of data. Difficult to avoid because the physical damage to the machine, in order to avoid accidental loss you are experiencing, we recommend that you also do data backup to cloud host.

Summary

Enable cloud services company, a large extent, is considering such a service can be more editing, cost-effective. However, such considerations if it is based on reducing the cost of security as, it is estimated that the boss will not agree with a lot of companies. Cloud services off the endless stream of events caused by concerns about the safety of the cloud.

Now, the solution can proceed from several angles, sure cloud services for enterprise-class customers, regular backups of the data of the cloud, with the second set of solutions, in order to prepare for contingencies. For cloud service providers, since a variety of off-network event is inevitable, it must consider a countermeasure to minimize the loss of their users, improve response efficiency off network events.

Government departments have responsibilities of oversight and remind legal legal cloud services were introduced and constantly improve, and to remind the user to one hundred percent reliable cloud computing services do not currently exist.
 

The previous day legend tiger 360 to push its own search engine, today, 360 of the search engine quietly on the line, some in the industry have been hearsay and start trial. 360 search enable domain so.360.cn two.
At present, 360 search interface is also very simple, subscript red below to design similar to "Youdao search". In addition, in addition to webpage search by 360 search provides search results, news search, MP3 search, image search, map search, ask search are directly linked to the corresponding classification of Baidu search, video search link to 360 of the original "360 video search".
In view of the line just 360 possible search, search technology and experience is still not perfect, so the 360 search is still retained the Baidu and Google search, the two search are integrated into the 360 search page, if the user feel dissatisfied with 360 search results, can be directly click switch to Baidu search or Google search.
From the micro-blog everyone to the 360 search engine test results, the 360 search may go is route Blekko (personal speculation), is also the only index authority sites to ensure that the garbage station authority and removing search results.
In August 10th, Cheng Lingfeng said in the micro-blog:
I heard that the general search 360 is about to launch its own domain name. Was supposed to launch the browser information recommendation based on, but not mature. Also heard on other search engine results in the "illegal" content or ads to remind users tagging.
At present, it said non-trivial, according to another Fenng in the micro-blog sources:
More hearsay about 360 search: everyone knows the address, now in the first test of water, its search results is not good enough, may and Bing do first cooperation. Real maturity in his own. 360 the stock price to rise.
In the afternoon there will be a small noisy can see: Sogou CEO Wang Xiaochuan said in the micro-blog:
By three stage rocket model, the 360 finally released universal search. Internet users have more choice is a good thing. But the search technology need long time of accumulation, we have to worry about the poor quality of the use of improper means to hurt the user. I'd heard the development process there are some extreme means to go beyond the bottom line "". Sogou search team will make a general evaluation on the 360 search quality, afternoon for everyone to send report.
At present the 360 official and Zhou Hongyi have not been disclosed more information.

Dispatch of sina science and technology on January 4th afternoon message, security issues feedback platform clouds (wooyun.org) today through the micro-blog said in a news release, network security vulnerabilities can lead to register a domain name hijacking is malicious.
Wu Yun said in the micro-blog, "the network be proof of the existence of security vulnerabilities, can be hijacked in the network domain name registration malicious users, completely repair loopholes in the nets suggest you Adsense and enterprises to increase monitoring of domain name".
In fact, the clouds are victims of this vulnerability. According to the micro-blog has revealed, this vulnerability to the attack, "and a long time cannot access and creates the actual loss of interest". The official further said, as network users will retain the right to prosecute.
In this regard, the lawyer Zhao Zhanling pointed out: if its loopholes instead of the user causes the domain name hijacking, 10 thousand nets should ask users to compensate for the losses. Otherwise, the user can through legal channels for all responsibility.
To date, all did not respond.

Netease science and technology news on January 4th message, according to foreign media reports, before the news Qihoo 360 and Google is expected to reach a search deal, may have on the Chinese search giant Baidu threat, but Qihoo has to ZDNet officially confirmed the news, said that the agreement with the Google does exist, but declined to give further details.
Bloomberg news earlier this week quoted the analysis of investment firm WedgePartners said, Qihoo and Google will collaborate in early 2013. Qihoo chief executive Zhou Hongyi said before, Qihoo to Google, Microsoft, Sogou search engine service companies have cooperation.

When ZDNet Asia linked to Qihoo aspects of the interview, Qihoo said: "between Qihoo can only confirm and Google cooperation does exist, but can not disclose any details of the information."
Citibank analyst Lee Act (Lee, Muzhi) to (RaviSarathy), and Ravi Saladi said, Qihoo and Google cooperation is bad news for Baidu is concerned. They reaffirmed Baidu sell rating, said this is because cooperation Qihoo search monetization and service and Google keyword.
If everything goes smoothly, Qihoo on Google cooperation for the first time. Qihoo has in their browsers before using Google search service, now it has been replaced by its own search service.
Qihoo has established itself in the field of software safety, the company has operations will be extended to other Internet services, such as browsers and search engine service. (West)
