Lutz put that together after we had a long talk 
about whether the concept of using 
dnssec-failed.org would serve to give people a 
level of comfort about the rollover. He posted it to our DNSSEC wiki page.

I didn't mention it in my message for a good 
reason. He need to change the text displayed if 
your resolver is DNSSEC-enabled. He says:

What will happen during the KSK Rollover for you?

Probably nothing, your resolver is validating 
DNSSEC correctly. Your ISP seems to make a good job in DNSSEC.

That misses the entire point of this issue. If 
your resolver is NOT validating DNSSEC, then that 
is the correct answer - you will be unaffected by the rollover.

But if it is validating DNSSEC, then you will be 
If it is not installed, you will be blacked out.

This is the entire uncertainty we have been 
discussing - the number of users who will find 
out they are DNSSEC enabled but not using the then current key.

What he should be saying here is that you reall 
need to contact your ISP (or whoever provides 
your DNS) and verify that they know about the rollover.

So it is prettier, but it currently sends the 
wrong message. When it is fixed, it will be a fine tool to tell people about.
