Tomas:

It's primarily a proof of concept site, to show that such an idea would be useful, but it has been running for over a year now and discovered many interesting hijacks (such as eBay/google/etc..). 

You're right that there is a glaring ommission, which is yesterday's youtube hijack.  This is due to a bug in the sub-prefix lookup code (which can cause the IAR to miss some sub-prefix hijacks), which I'm currently fixing.  Once that is done I'll rerun the IAR over yesterday's logs and it will show up.

This is a very interesting site. However, I notice that, in the "all in
the last 24 hours" it doesn't show the YouTube hijack. It does have a
lot of entries for 17557, most recently on 2/17.

How reliable is this system?
