Change in host / registrant

[mysty]

A couple months back we were having major issues with our hosting provider "excessive down times, bad public relations toward the hosting provider, and also provider being exploited along with our site", so we decided to change hosting companies. Somehow during the change, the registrant information (owner name only, address, contact, phone number, etc stayed the same) also was changed. The registrant was changed in error as our new hosting provider took the name of who was being billed as the registrant "we have the hosting provider renew the registration". Since then we have noticed links as seen when doing a link:http://www.domain.com decreasing, but when looking in the Google webmaster tools, we see the number increasing. Our PR has recently dropped as well. Would you say this is due to Google de-indexing our site due to the change in registrant or for some other reason? And if it is due to the registrant, what would be the best way to fix it? We do not prefer to change the registrant again as we feel it would cause more confusion and being banned from Google. We have no messages from Google or errors in page crawl showing in our webmaster tools. We have done a little bit of research on this and some of the feedback we are getting is this domain is as good as trash due to Google thinks it has been sold and unless we change the content of the page 100% and start over, it will slowly drop off to 0.

I don't think changing registrant or host should effect in ranking position, however make sure you've done everything right while you shifted to new host and consider to organize your link.

But when the registrant changed, the site owner name "organisation name" was changed. I have read other places where Google may view this as change in ownership of the domain, and when ownership of the domain changes that Google tends to de-index the site. "as if the domain has been sold'

consider to organize your link

I'm not quite sure what you are referring to there.

My question is what would be the best way to handle this mistake / error? I do not want to change the registrant as this will just add to the confusion. I'm not sure if I should file for reconsideration as there may be other reasons why this could happen, as in links no longer being counted, etc. I was asking if other people here thought that by having the owner of the site changed, 1 - could it do this, 2- what would be the best way to fix it without changing 100% of the content.
