Is it common for a site to disappear and reappear in the SERPS?

I have a site that's 2 years old and it completely disappeared from the search results. It wasn't a manual action because I never got a notice in webmaster tools.

Could the site reappear? A lot of people on Odesk say the site will reappear after a few days.

2 of my sites hit yesterday and they are not showing anywhere on google. They are still indexed but there is no manual action on webmaster. i think they are not coming back.

A couple of years ago, my first agency experienced this issue. There were a few queries I kept a sharp eye on, and the site disappeared for most of the day. The site couldn't even be found for the company name. Later in the day, the site returned to it's previous placement.

That happened a few months after noticing a couple clients received referral traffic from banyan.google.com, via Google Analytics. Basically, The Eye of Sauron was watching the properties. This didn't appear to bother the higher-ups, but it bothered me.

I had advised that they stop doing what they were doing, but they could see no ill end to it. They went on to survive the first Penguin. Penguin 2 proceeded to knock them out of the running. After I left, there was no recovery. They were happy to continue on their way.

Your site may return, but it's unlikely. Are the people that say it will return in a few days the very same that put it in the situation?

I had a website that disappeared from the search rankings one morning, then a couple hours later it re-appeared. No manual actions were taken.

IF you had a website disappearing today (or yesterday possibly), it could be a Penguin 3.0 penalty as it was released within the past 24 hours.

Thanks,
