通話、いまだ利用しづらく　データ通信「おおむね回復」―発生６０時間、復旧は未定・ＫＤＤＩ障害

　ＫＤＤＩの大規模通信障害は、発生から６０時間近くが経過した４日午後になっても、携帯電話の通話が利用しづらい異例の事態が続いた。復旧作業は３日夕までに終了し、同社は４日朝にデータ通信について「全国的におおむね回復している」と発表した。ただ、ネットワークに問題がないかを確認する検証が継続。通信制限の解除には至らず、全面復旧のめどは立っていない。（2022/07/04-12:43）

KDDI Corp. customers still had difficulties making phone calls on Monday afternoon, nearly 60 hours after the outbreak of the large-scale network disruption across Japan.
   The major Japanese telecommunications carrier said its data communications services had been mostly restored nationwide as of the morning, following the completion of work to resolve the problem by Sunday evening.
   Still, KDDI continued to restrict communications due to work to verify whether its network functions properly. It remains uncertain when its services can be fully restored.
   The major service disruption started around 1:35 a.m. Saturday (4:15 p.m. Friday GMT). A glitch happened during work to replace network equipment, affecting other devices in a chain reaction.
   The problem temporarily caused as many as 39.15 million subscribers nationwide to have difficulties using voice call and data communications services.
