What could this mean?

If you look at the video for Invocation, and hold your mouse over the screen, it comes up with this link:
http://www.warprecords.com/666/

When i punched that in, it said:

Forbidden

You don't have permission to access /666/ on this server.

Any reason why? 666 is the number of the devil, and the length of their geogaddi album. Anyone know what it could mean?

It just means the original file location has been removed.

The proper link is: http://archive.warp.net/666/
