This is the most discussed topic on almost every SEO forums.
Google filters newly created websites from results so website traffics and ranks affected from this effect.
So, to recover from this, you need to create useful content and strong back links for your website, to get index and crawl by Google.
There is no such thing like Google sandbox. Ask yourself if a new website would have got links from CNN news, NYT, BBC, New York etc. within a first week of it's existence, would G Sandbox apply to this website. I think not.
So what is google sandbox? It is lack of Domain Authority (or PR if you're old ). High DA is like a super power it gives you more resistibility to Google Penalties / Google Trust you more.
