TOKYO — Web search service was suspended for five and a half hours Sunday on the Yahoo! Japan portal due to a computer server glitch, Yahoo Japan Corp said.
The company said it has already taken measures to prevent a recurrence and that the problem was not caused by a cyber attack. The search function was out of service from 9 a.m. to 2:30 p.m.
