I thought Google doesn't give a penalty for hosting downtime if the site comes back not long after. The past week my site had dowtime 2 times. I checked my rank today and noticed that some of my keywords dropped. Checked my site and sure enough hosting was down again, probably was already down for a couple hours. I am sure the drop was a result of that, so you better get a good hosting!! Btw, did anyone see this and knows how long till a site comes back from a "penalty" like this?
