google stopped crawling: can be a dns issue?

[manores]

Hi all,

I have a PR 5 website and or about a year, and the homepage used to be crawled every 1-3 days. For about 10 days, google stopped crawling the homepage and put an older cache (a cache about a month old).

a link to search in Google returns 127 links. And there are many links (about 1000) that are PR 3 and lower. Also, i checked the PR5 sites that link to my site and their homepages are being crawled regularly. So I don't understand why my site is not being crawled.

Anyone experiencing such a thing? May it be a spam penalty? I have no spam like activity on my site, but I'm not sure about. I have text navigation which are optmized, and also SEO is applied in all pages but a *clean* SEO. What may be the case?

The only change i have made is purchasing a DNS service from another company and adjusting nameservers accordingly. May it be the case? MAybe Google cannot reach my site and crawl it. How can i make sure that Google is able to reach my site to crawl?

Any idea/help is greatly appreciated. Thanks for your time in advance.

Welcome to Webmaster World, manores.

This is really beyond my technical insight, but I have heard that changing DNS service really can be tricky and AFAIK it is indeed possible that the source of your trouble is here.

We have quite a few members with deep knowledge about this stuff. I hope one of them will chime in.

When did you change your DNS?

Are you sure that Googlebot dint hit the new IP one single time?

Whats lying at old IP now? I mean anything you left there?

Others have said that you should leave the site running at the old IP until Googlebot hits the new one.

kaled:
on shared servers/IPs this is not possible.

I have changed DNS and IP also. Googlebot is crawling my site regularly but I got a PR0 (before PR6) and the link: command shows zero backlinks while there are about 1900 backlinks. Rankings haven't changed significantly, only the normal flux so I don't believe it is any kind of penalty. The curious thing is that I get a fresh date every day and google is crawling and crawling but PR is still 0.

BTW: This is not the first site I moved to a new serverī/IP/DNS. I had never problems with a site, this is the first time. Maybe it was because the transfer fell in the time of the last PR update.

Don't believe toolbar PR, believe your SERPS.

yes, kaled that's what I think too. But many people who were used to link to my site remove their links now because they have fear to link to bad neighboorhood.
They are so focused on this green little thing , damn. ;-)

The only thing which causes a unpleasant feeling is that the link: command shows zero backlinks.
