KDDI aims to restore service Sunday after 40 mln users affected

KDDI Corp said it aimed to restore services by Sunday evening after nationwide network troubles affected up to nearly 40 million users, making calls and getting online difficult for more than a day.

The disruption, which started about 01:35 a.m. local time on Saturday , have also affected a wide range of services, from weather data and parcel delivery to banking and transportation that use KDDI networks.

"We deeply regret this as a telecommunications carrier in a position to support critical infrastructure and provide stable services," KDDI President Makoto Takahashi told a news conference, adding that the company takes it as a serious accident.

Around 70% of services have been recovered by mid-morning on Sunday and KDDI plans to recover the rest by around 5:30 p.m. (0830 GMT), Takahashi said.

Up to 39.15 million users have been affected by the failure that occurred after the voice call switch system experienced congestion with data beyond processing capacity, the company said, adding the detailed causes were still been investigated.

The widespread network errors have disrupted transmission of the weather data at the Meteorological Agency, automated teller machines at a regional bank in central Japan and the online system to track the delivery of parcels at Yamato Holdings, according to Kyodo news agency.
