Hi, today all the whitehat websites associated in 1 of my Google Webmaster Tools disappear from SERP. 1. I cannot find my website on #1 even when I do an exact domain name search such as "blackhatworld.com" on Google. 2. I cannot find my website on #1 for the term it use to be #1. 3. I hardly find my website even though I use the "site" operator. I don't think this is Google dance because this involved all the website in that Google Webmaster Tools. However, there are error on the Dashboard saying that DNS Lookout Time Out since several days ago. Do you think this is the problems? All my sitemaps are also inaccessible by Google bots. Several weeks ago I change from Platinum SEO Pack to Yoast SEO, do you think this is the issue as well? Most importantly, do you guys think I can get back on the game?
