今天连续收到两封这样的邮件，标注了不同的文件丢失：
Over the weekend, while making upgrades to the Bitbucket platform, non-source code binary files were permanently overwritten for a small number of users who use the downloads feature. We are contacting you because your files were impacted.
Below is the list of your files that were affected. If you want to make the original files available for download in Bitbucket again, you will need to re-upload them.
We recognize the trust you place in us with your data and take that responsibility seriously. We have systems in place to protect the integrity of your data, but those failed us in this instance. We sincerely apologize, and are improving our operational procedures in order to prevent something like this from ever happening again.
Please email support@bitbucket.org with any questions or support you may need – we're here to help in any way we can.
Sincerely,
The Bitbucket team
