January 24, 2019 – The communications ministry last night urged SoftBank Corp. to strengthen measures to deal with service outages after the company suffered a major system disruption last month.
The Ministry of Internal Affairs and Communications instructed the mobile unit of SoftBank Group Corp. to speed up decision-making and cooperate more closely with equipment suppliers to quickly restore mobile phone and data services in the event of an outage.
The massive service disruption on Dec. 6, caused by faulty software provided by Telefonaktiebolaget LM Ericsson, affected around 30.6 million service subscriber lines for about four and a half hours.
Japan’s third-largest carrier by user base put information about the disruption on its website, but the ministry instructed the company to use its service shops to inform customers of system failures more swiftly.
“We take the instruction seriously and will ensure similar incidents will never occur,” SoftBank said in a statement.
