Frequent and large-scale network failures, why are operators so "overwhelmed"?

The recent situation of telecommunications has a bit of a meaning of "the house leaks and it rains overnight". In the case of the Xi'an Yicaitong frying pan incident, it is possible that the relevant departments have not yet completed the general ledger of the Xi'an Telecom Branch after the autumn. Immediately this morning, a large number of users on Weibo reported that the telecommunications network was disconnected, affecting many cities across the country.



This is not good. I wish China Telecom would like to mention the hot search on Weibo. To be reasonable, in fact, no matter what industry you are in, it is inevitable that failures will occur due to various accidents, which will affect the lives of residents. For example, if the power industry fails, the power will be cut off, if the hydraulic industry fails, the water will be cut off. If the communication industry fails, the network will be cut off. The frequency is not high, the impact is small, or the operator can repair it in a timely manner and recover quickly, and the user's tolerance is still very high.

However, there are frequent failures, and even companies that cannot even come up with a reason to convince the public, it is time to reflect on their service attitude. The topic goes back to the operators. The three companies have had network failures in recent years. The editor went to understand that the latest reports on large-scale network failures by China Mobile and China Unicom were in 2018 and 2019 respectively.

As for telecommunications, you don’t even need to search for information. As far as the editor’s impression is concerned, in the past six months, firstly, the Chongqing telecommunications home loan concession certificate was suspended; then the Beijing Microsoft line was unplugged; Xi’an one yard The collapse and collapse made the city of Xi'an relive the pain during the outbreak of the epidemic; in the early morning of last night, from the coordinates of telecom netizens from all over the country, including Beijing, Guangzhou, Hangzhou, Changchun, Urumqi and other places, there were network disconnection problems. .

Nationwide network outage, what happened to telecommunications?
According to the telecom official, this nationwide network failure is an optical cable failure. Presumably there are a small number of users who believe this statement. According to the editor's observation, the comment area on related topics is a big wave of netizens complaining.

The editor can't accept this statement for the time being. From my personal point of view, so far, I haven't seen any reports of anyone digging up the optical cable. The ipv6 is normal, and the ipv4 and ipv6 links are shared. It can only be said that there is an ipv4 operation and maintenance problem, or the ipv4 device software is faulty. Moreover, NOC dispatching and routing explosion seems to be the daily operation of telecommunications.

Many people should know that ChinaNet of Telecom is AS4134, and CN2 used as a boutique network is AS4809. These two are the AS numbers of the backbone network. AS4809 has a very low failure rate. According to professionals, AS4134 has always been the network with the highest failure rate, and it can still fail for a few hours and no one finds it until customers report for repairs.


So what will be the real cause of the nationwide telecom network failure? It is unknown, and according to the official attitude, it is not easy to make more specific guesses. The editor believes that the most important thing is that telecommunications should correct their work attitude and re-examine the heart of serving the people!

When will Telecom re-examine the heart of serving the people?
A few years ago, Guo Shenghua, the godfather of hackers, once sighed that the importance and influence of the Internet are growing. So now, users' demand for the network has undoubtedly reached a peak, and this demand will continue to peak again and again. The network is as important as water and electricity, and at some special moments it is even closely related to the safety of human life.

For example, the miscarriage incident of pregnant women in Xi'an shocked and hurt the whole network. During the critical period of the "resurrection" of the epidemic in Xi'an, the collapse of Yicaitong, which was mainly responsible for platform construction and operation and maintenance by telecommunications, caused a pregnant woman to be stopped at the door of the hospital. outside. There are even more than one incidents like this, and the words of the parties' painful complaints are piercing through the heart.



The editor believes that even if users do not pay much attention to the real cause of network failures, as a network operation and maintenance party, telecommunications should be clear about the root cause of the problem, strengthen technical support, and do not repeatedly drop the chain at critical moments.

Providing ubiquitous network services is the obligation of operators and the foundation of their existence. Network security is a red-line task. We hope that China Telecom will continue to tighten the string of network quality and review the heart of serving the people. It is also hoped that the lessons learned by Telecom will make the other two operators sound the alarm.
