First of all, you mixed up some of the letters. Your URL says "LVSP" but you are searching for "LSVP"
Next, LVSP is an acronym for Linux Virtual Server Project
So I did a search on Netcraft, and found that search.live.com is running Linux.
Is Microsoft running Linux? *gasp* Is that the TRUE conspiracy here? NOT. Actually, they've been using Linux for years.
So my conclusion from all of this is that MSN is experimenting with Linux Virtual Server Project, and well, computers being computers, things aren't going as planned.
