Greetings!

Recently I had a few problems with a few sites I just start to handle (all on same IP):
www[dot]pmoz[dot]org
www[dot]pro-board[dot]com
www[dot]jdhealthcare[dot]com
Recently they got de-indexed by MSN, for a reason that remains wierd to me. Even more a few other sites that linked to these ones (located on different IPs) received a penalty (drop in SERPS).

Do you have any idea why this happend - as far as I know the sites are legitim and no black hat seo is used.

Please let me know if you notice anything that may result in this MSN ban / penalty.

Thank you in advance.

Sounds like you might have incurred a penalty for excessive cross-linking. Were all the sites cross-linked?

yea that may be the reason coz somewhere i had also read that msn is applying some kind of penalty to some sites for excessive reciprocal linking

Maybe you have some link exchange issues
Maybe your server get down for more time...
If i had more sites deindexed i could answered exactly...

Maybe it realized that your site uses some random content? (if the spider checks the same site twice and every time sees different results i think you can be in trouble)

MSN deindexed one of my sites too some time ago.
