Site is gone from Yahho and AV.

I changed IP. Can that be the reason?

Hi,

I launched a brand new site/domain 6 months ago and it's been OK ranked on Yahoo and AV. Last weekend I transferred the site to another server (same host) and got a new IP, pointed the domain to the new DNS and had no problems: it could be accessed at the new location/IP through the domain URL after a day.

But at the same time, the site disappeared entirely from Yahoo and AV and it's still not found.

(I use Advanced Web Ranking to check).

But I also entered Googles AdWords program a couple of weeks ago with this site...

Could any of the two recent actions affect the absence?
