My web site is under attack

The bandwidth usage raised from 0G to 12G during last week. Is there a way to protect my site？ Thanks!

May 8th was when bandwidth logging was re-enabled globally, which would by why your bandwidth started rasing. However, I have seen the same ip-address downloading the same file off your site repeatedly. (This has been 8 times I've seen it in about 5 minutes).

The file request is for "/pblog/attachment/Mon_0612/1_3_6810af4a9d6d6a2.mp3", and the IP address will be emailed to you. You can check on this yourself.

Thanks, just blocked that IP and delete mp3, hope everything will be fine.
