PR Killed!

Host hit by hackers PR went from 4 to 0 overnight

[buzzbeat]

Our host got hit by a bunch of Morrocan hackers who replaced our home page for a few hours. Soon after we got the right index page up the host must have reset the servers because it reverted to an old index page (index only) and old password info etc...

The result, my months of PR work were kiiled. It dropped from 4 to 0 overnight. I checked in Google's cached version and it was 0 there as well. Intersetingly, our interior pages still retain their PR scores of 3.

Any idea why Google did this? Will it come back or did we get penalized some how?

Your thoughts and advice please...
