Yahoo results changing and site update problem

[nsm]

Hi,

I have 2 questions:

1.
I submitted my site to yahoo about 5 weeks ago and sometimes my site is listed on the number one possition and other times it's not listed at all.

I type in the keyword phrase i optimized the site for and it's on number 1
I type in this : site:domain.com and the sites appears as listed.

a few minutes later or when i check again the domain is not listed at all if i type in the keyword phrase or site:domain.com

How is this possible?

I did change the DNS to move to a new server, but it was happening even before i changed the dns. ( i think not sure )

2.
An other site of mine is listed for some time on yahoo but after my last update yahoo does not update the meta tags ( title, keywords, description etc. , etc. )

Why is this happening?

I appreciate your help

Thanks,
Norm

My 1st position domain stays there now. It had to do with the DNS

Does anybody know what the problem could be for the following:

A site of mine is listed for some time on yahoo but after my last update yahoo does not update the meta tags ( title, keywords, description etc. , etc. )

Thanks
