A networking problem was found at 7:30 a.m. after a device used in its network connection broke down, according to Amazon Web Services. The company said the system was restored in the afternoon.

SBI Securities Co. and Rakuten Securities Inc. were also hit by the glitch as they receive stock quotes from a company using AWS.
Japan Airlines Co. said it had trouble in a system managing the weight of air cargo, but it did not impact its passenger flight schedules.
