"Although the reality of you can not be a neighbor with Ma Yun, but the site may be adjacent to Taobao" This is the Chinese million network to the customer, the site host migration notification mail in a very sensational words. Hangzhou million network cloud machine room into practical, China million network has successively many batches of host products have migrated to Hangzhou backbone Cloud room. This is also the Alibaba strategic investment million network, coincided with the cloud computing slowly commercial, China million network of a major technological innovation. According to China million network plan, the most recent host product migration plan will be December 2 December 4, in the mail to agents and direct customers, said the migration will lead to some sites for 36 hours inaccessible. For sites that are still struggling to rank, the impact of a 36-hour access outage will be fatal. The author believes that if you do not take care of the emergency work, some sites are likely to suffer the right to decline. And the only way to solve the problem is to ensure that the site data migration during the site can be uninterrupted access, and the reopening of the emergency bridge host is probably the only coping strategies.

Full backup of Web site data

There are many ways to back up a Web site, with regular incremental backups of the database and Web page files, and local backups via a specific program's server. There is also a full backup of the site data and off-site backup, where the number of sites in full off-site backup is the safest. Because host migration means that the site will be interrupted, make sure that you have a full and full backup of the site data on the original server. The specific way is through the FTP tool, from the original server in binary way, the Web site data full download, and then passed to the new host space. Not only the site backup to complete, site content upload also want to complete, must carefully check to ensure that after the replacement of the host site all the content can be normal access.

Second, do the content migration ahead of time

It should be understood that DNS parsing is never synchronized. In other words, we do a good job of domain name resolution changes, seemingly normal access to the site, because the Internet has many nodes, and in some places may not be accessible, in general, DNS global synchronization takes approximately 48 hours. Because the site has been replaced by the host, it is inevitable that the original site to resolve the domain name. In order to ensure that any corner of the world can be normal access to the site, so you need two days ahead of time to migrate the site data. Because the only way to do this, site access will not appear blind spots. The purpose is to change the host and the new domain name resolution operation, the original site host space still need to maintain a few days of normal access.

Third, the maintenance work to follow up in time

Site content Data migration will inevitably bring the site host IP changes, which in some cases in fact, the weight of the site has an impact. Because the search engine is the domain name to carry on the inverse analysis, obtains the IP address to crawl retrieves the website content. Sudden Web site host changes, always need a time to adapt. If the site host changed, and the content update maintenance also stalled, will inevitably bring the search engine suspicion. Shanghai website Construction Company Pilotage Technology (http://www.joyweb.net.cn) recommends that, after the replacement of the host, the site maintenance personnel on the one hand to continue to observe and carefully check the operation of the site, on the other hand, as always, the content of the Web site regularly updated maintenance. This is the only way to minimize all risks and potential losses after a host replacement site data migration.
