Re: YouTube IP Hijacking

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.
