http://everevo.com/event/1334 第2回『いまさら聞けない!システム運用・管理のコツ』
ホスティングサービスは、お客様のサーバをお預かりし、24時間365日の運用支援を行うインフラサービス。現場エンジニアはトラブルにどう立ち向かうべきか「サービス提供事業者視点」で取り上げます。ネットワークやサーバ障害の対応事例を(公開可能な範囲で)皆様と共有し、日々の業務に役立てることが出来ればと思います。

7. ―Don't forget. always, somewhere,
someone is fighting for you.
―As long as you remember her.
you are not alone.
忘れないで、いつもどこかで誰かがあなたの為に戦っている。
Operation 彼女を覚えている限り、あなたは 人じゃない。
彼女を覚えている限り あなたは一人じゃない
