Just a week after I wrote “Uh Oh, Gmail Just Got Perfect” a number of users started complaining that all of their Gmail emails and contacts were auto deleted.

Google’s official policy is that once emails are deleted, they are gone forever.だそうで、これは困ったことだ。


Regretfully, a small number of our users ― around 60 ― lost some or all of their email received prior to December 18th. Once we found out about this issue, we worked day and night to confirm that only a few accounts were affected and to do whatever we could to restore as much of the users’ accounts as we could. We’ve also reached out to the people who were affected to apologize and to work with them to restore the email from any personal backup they might have.

We know how important Gmail is to our users — we use it ourselves for our corporate email. We have extensive safeguards in place to protect email stored with Gmail and we are confident that this is a small and isolated incident.

てな感じで、約60人の12月18日以前のメールが消えてしまったことを確認し謝罪したとの事だが、復旧はユーザーのBackupに頼らざるを得ないと掛かれているので、それがなければアウトということだ。「a small number」とか「this is a small and isolated incident」などという言い方は逃げ口上にしか思えない。

メールに限らずDoc & Spreadsheetなど、個人の情報をGoogleに預けてしまう危険性については、GoogleがEvil化した場合を想像していたものの、今のところあまり危険性は感じられないものと判断していたが、このように何らかのシステムトラブルや人為的ミスについては心配していなかった。が、どんなに優秀な人材を確保していたとしても絶対に安全なものなどないのは当たり前だということを改めて思い知らされた次第である。
