It's here today in the UK. I think it was ten site links (two per line) for the number one site in the search I did. Just made the same search and the links are still there - eight actually, two per line with "show more results from #*$!xx.com". When it fisrt happened I thought I was on google by mistake.
If the mods let me, I'll give the search term. It happens on both Firefox and IE.
Stangely if I alter the search slightly the same site still comes out top but not with the site links.
