I have run into something that I have not experienced before and I’m hoping someone can offer some insight. About a week ago a put up a HubPage and it was indexed and appearing on the first page of Google search results for the intended keyword within 2 hours. So far so good… It bounced around on the first page for a few days and then disappeared. It not only disappeared but now it is appears that it is no longer indexed. I can’t find it using any of the advanced operators (site:mydomain, inurl:mydomain, info:mydomain, etc…) The fact that it's no longer indexed really has me stumped. Any ideas on what might cause this?
My guess...you are accessing more than one data center. Since the page is so new, I guess that first data center had it indexed before the other data center you accessed. Give it some time and it should be indexed in all data centers eventually. With hubpages it helps to do some link building through things like social bookmarking.
