Didi 11.27 “P0 level fault” possible cause analysis
Note: P0 means the problem or fault with the highest priority.
The winter in Beijing is extremely cold. Just after 22:00, I returned home after a day of overtime work, only to find that Didi’s travel service was out of order. Alibaba Cloud has just finished hanging up, Didi hanging up, this is really an eventful winter.
The impact of this failure was quite large and lasted for a very long time.
At this point in time, it is estimated that many Didi students were off work and could only deal with the problem remotely through VPN. It was found that VPN services were also affected.
Unable to connect to the online server to troubleshoot positioning issues, I had to take a taxi to the company.
I took a taxi to the company and found that Didi was down and unavailable. I was embarrassed. This made it difficult for Didi students to log in to the server and locate it.

The Internet industry is really difficult this year. There are rumors of layoffs and different opinions. It is said that the growth of the Internet is not as expected, and the existing operations no longer require many manpower.
Alas, when policymakers don’t understand how “quiet years” come about, that’s when fewer and fewer people “move forward with heavy burdens”.
Finally, when it comes to an avalanche, no snowflake is innocent.
