Cause Analysis of slow website snapshot

First, let's take a look at some reasons why someone else says it is not updated on the Internet:

1. The content quality is not good. For this blog, there are more than 90% of original content, or you can say that it is pseudo-original content, because there are many theoretical knowledge points on the Internet, I just repeat my practices and opinions. However, this should not be low-quality content, so this can be ruled out.

2. The number of external links is unstable. This should be ruled out in needless to say.

3. The website is affected by links. Several snapshot updates in the URL have not been very powerful. This is the case for several months. This time, because this snapshot has stopped updating, I have notified the other party to remove several friends, but the snapshots have not been normal for a week. In addition, I also checked the sites on the same server and found that most of the snapshots are normal and there is no involvement.

4. For website security problems, this blog is not infected with Trojans, and there is no hidden link to use the lynx check. Security can be disabled.

I still cannot find the problem in the above aspects. In fact, I found that snapshot 6.29 is not the case for me alone. When I searched Wenzhou SEO in Baidu, I still had a few days to stay there. Well-known forum WHY today's snapshot is also in 6.29, last night in a SEO group chat, found a group of friends said they showed that the day of fast care is 6.12. Like http://www.111cn.net

What problems does this mean? As you know, searching for large amounts of data captured every day is saved to the server, and these massive amounts of data need to be stored in countless different servers for your search and call. You can also obtain a proof from the figure above. In general, they are all synchronously updated, but why is the snapshot date I searched different from that of my group friends? Is it possible to search for other problems such as data loss and data errors? Is this snapshot not because of the original cause? I don't have to worry about it. Recently Baidu often experienced problems. I believe everyone knows that, for example, the recent SITE error and the previous 5.20 ranking problems. This also shows some technical problems in large-scale data storage and access.
