2/22(金) 午後12:44 (PST) (日本時間 2/23(土) 午前5:44) に、Windows Azureストレージで、全てのサブリージョンにわたって、SSL証明書の期限切れによる、HTTPSトラフィックに影響を与える障害が発生しました。この障害は、HTTPトラフィックには影響を与えませんでした。我々は、影響を受けたクラスター上でSSL証明書を更新する修復手順を実行し、全てのサブリージョンで99%以上の可用性を回復しました。今後24時間、ストレージ サービスとSSLトラフィックのの健全性を監視し続けます。この期間中、お客様が断続的なエラーに遭遇する可能性があります。今回の障害でご迷惑をお掛けしたお客様に、心よりお詫び致します。

On Friday, February 22 at 12:44 PM PST, Storage experienced a worldwide outage impacting HTTPS traffic due to an expired SSL certificate. This did not impact HTTP traffic. We have executed repair steps to update SSL certificate on the impacted clusters and have recovered to over 99% availability across all sub-regions. We will continue monitoring the health of the Storage service and SSL traffic for the next 24 hrs. Customers may experience intermittent failures during this period. We apologize for any inconvenience this causes our customers.
