Friend no longer ranking for own site name

My friend owns Virtual Pet List.com and now he no longer shows up for his own keyword:

http://www.google.com/search?lr=&ie=UTF-8&oe=UTF-8&q=Virtual Pet List

What could be the cause of this?

 

Hi , it comes up #1 when I search..
Could be some Google Index update you're seeing on some DC...

On google.ie ( Im in Ireland ) i dont see the site at all...

Google Dancing me thinks!

Cheers!

 

#1 for me too.

Not unheard of though. Take my name for example. I started using Tekime almost 5 years ago, when it didn't even have a Google presence. I own www.tekime.com, but it's #10 in Google now, preceded by even some of my own sites, which link back to tekime.com!

Dance away...

 

That's weird, must be a problem with a ton of the datacenters.

 

#1 for me, it's not a DC problem, it's a dumb dumb problem.

 

so, should he worry or do anything about it?

 

I think you should try to ride it out for now. I even go up and down every day.
