We launched a brand new website on the 7th of Jan. We directly created a new Google Webmasters Sitemaps account, and uploaded a sitemap. On the 8th of Jan, we found that our URL was UNREACHABLE in webmaster tools, with a DNS error. We checked all our settings and did not find anything wrong. A few days ago, the homepage has been indexed and was showing up doing the command site:www.site.com Today it completly disappeared from all datacenters, the sitemap status on the webmaster tools is still OK, with 1000+ urls submitted. We got hits from googlebot crawling our pages, but the homepage has disappeared.
Any ideas? have we been banned by google? Thanks in advance for your help
