I submitted my site and it seems to work OK, created sitemap with free generator on Google, then submitted sitemap to public_html folder. Checked it on google webmaster tools and I am now getting this error message "DNS lookup timeout! how can it be resolved, what can I do? Please advise.
Since yesterday everything was working properly in my site www.ellinas.org greek e-shop, portal, live cam, online games etc but today i checked google webmasters tools and i see that the above dns error is there and that google has not indexed any of my sitemap pages! The day before yesterday it had indexed 60+ pages! Before some days my provider changed a datacenter and they changed my website ip! They have done all proper dns declarations so my site is on air and can be visited properly however i do not see the googlebot visiting my pages anymore! Please help give me your opinion should i do something to fix this problem or should i wait until the google webmasters tools are also updated with the new ip of my web site! Please take notice that google does properly verify my site with the included html they need!
Any changes to DNS Records can take up to a week for the entire interent to notice. It is called propagation. While most of the internet will pick up the change in a matter of hours to a couple of days, some places will take longer. Give it a few more days and if webmaster tools are still showing that error, contact your provider.
Without more information, there is not much anyone can help with. Are all of your DNS Records set up proprly? Is your name servers set up properly? Did you recently make any changes to your DNS Records pertaining to your site's IP Address? There are many free tools out there that can check your DNS Records for any potential problems. Start with that and see what happens.
