KDDI, a leading Japanese telecommunications company, has provided the government with a thorough action plan, disclosing it had developed new methods for fast recovery from network facility congestion following a major network outage in early July.
More than 36 million people were impacted by KDDI’s most recent service outage, which began on July 2 and continued for more than 61 hours till July 4. A significant occurrence under the telecommunications business law was recognized by the government since it was one of the biggest telecommunications network failures in Japanese history.
On August 3, the ministry of telecommunications issued a rare administrative guidance rebuking KDDI. It instructed the carrier to take precautions to avoid another incident. But given that previous outages to mobile phone services, including those for emergency calls, lasted less than an hour and did not affect nearly as many customers, it seems unlikely that this new malfunction would be regarded as a severe event.
Accordingly, KDDI submitted a ten-page report in response to a request from the Ministry of Internal Affairs and Communications that was based on an analysis of the work standards and methods for maintaining communications equipment as well as the design of congestion detection and control.
KDDI is working to tell the industry about the incident and “formulate standards for the prompt and proper provision of information when failures occur” in order to fix the problem and stop it from happening again.
According to the operator’s inquiry, the outage was brought on by the nationwide relay network’s core routers being maintained using the wrong work process manual, which resulted in a significant routing configuration error.
To prevent such issues when doing equipment maintenance, KDDI established new work procedure management regulations and approval techniques in July.
Additionally, a working group was formed to suggest ways to enhance customer interactions during outages. KDDI has also outlined intentions to make amends for the almost 36 million customer who were adversely affected by the outage.
