网站被“回滚”

昨天突然发现，自己的blog的数据似乎被人改过了，“回滚”到了前几天的状态，几天内的若干个回复不见了（这几天内未有新的blog）。

发信询问主机商，主机商答复如下：
Yesterday around 1:00pm Pacific time, there was total power blackout to much of Los Angeles, affecting at least 2 million people, due to human error at a DWP plant. While power was out, the three levels of backup generators used to provide power to the building where our server farm and others are housed and specifically to our network also experienced problems, and all failed after a short period of time. This cascade of events and the ‘trickle-up’ DWP effort to restore power caused intermittent inaccessibility and data loss throughout the evening. If your website or server is not back up now, either its data is being restored from backup or it is still waiting for continuing power cycling throughout our network before it is fully accessible.

We understand and apologize for the frustration this has caused and we are working with the operations team for our building to repair all problems with the generators used to ensure power to our building to prevent this type of incident from occuring again in the future.

如果有留过言的朋友发现自己的留言不见了，不要怪我乱删，呵呵。不是我删的，是主机商rollback了我的数据。
