振り込み２７００件に影響　みずほ銀、３０日の不具合

　みずほ銀行は３１日、他行宛て振り込みが３０日に一時利用できなくなった不具合について、影響が生じた取引件数が約２７００件だったと明らかにした。不具合は既に復旧しており、同行は原因について、「システムの障害ではなく、夜間・休日の入金処理の設定に関する人為的なミス」と説明している。
　みずほ銀では２０２１年、２月以降に計８回のシステム障害が表面化しており、管理体制が改めて問われそうだ。
　今回の不具合は２１年１２月３０日午後３時半ごろ発生。約１時間にわたり、現金自動預払機（ＡＴＭ）やインターネットバンキングによる国内他行宛ての振り込みが一部で利用できなくなった。約２７００件のうち、約２４００件は同日中に振込先への入金手続きを完了した。残り約３００件の処理は３１日以降にずれ込み、一部の入金は２２年１月４日付になるという。（2021/12/31-14:49）

Thursday's service disruption at Mizuho Bank has caused delays in about 2,700 fund transfers to other banks, Mizuho officials said Friday.
   The bank's services for money transfers to other banks using its automated teller machines and online banking platform became partially unavailable for about an hour from around 3:30 p.m. Thursday (6:30 a.m. GMT).
   Of the 2,700 transactions, 2,400 were executed within Thursday, with the remainder set to be completed between Friday and Tuesday, according to the officials.
   The disruption "was not caused by a system glitch but by a human error in settings related to the processing of money receipt transactions at night and on holidays," an official said.
   At Mizuho Bank, eight system glitches had occurred since February 2021. In response, the Financial Services Agency has issued business improvement orders to the bank and its parent, Mizuho Financial Group Inc. .
