"Hey, manager, and now we can not access the site properly, we abnormality is detected by background log!"
"Give me a specific abnormal shots right away!"
"Well ... Screenshot been sent to you! " "
... " "
immediately verification database, data is written to the nearly one hour, the analysis! "
After receiving this phone, all engineers across the company into a state of high tension, and held an emergency meeting to deal with, from the network to a variety of middleware and then the program code analysis.
1 minutes ... two minutes ... 10 minutes later.

"Hey, manager, at the moment all our services all has returned to normal, log, database detect all normal!"
"Nani ??????"
"What did you do the operation deal with it? " "

After that is dependent on SQL injection caused a "disaster", the program after a quick upgrade iteration, will make up their bug, it has not been a problem similar exception.
通过该事件，虽然运维工程师是在未经运维制度流程审批（注：一个从事IT行业多年的企业，一般都会有操作任何数据、服务器等的规范流程制度。），就将携带病毒的数据删除，但是有了此举，才得以我们没有损失任何数据，功大于过。
最后，公司决定对运维工程师进行全体通告表彰并加以奖励！
