It was registered 2 days ago. But in IFN table, the .com is in a GREEN check. Well I found some case with IFN. Some also saying it's in RED color, but it's available for snapping. So it's not accurate sometimes...
We try to be as accurate as possible when it comes to domain availability, for that reason we query the WHOIS servers for every single domain, which is about as accurate as you can get.
But due to the amount of domains (~ 3 million), we cannot pre-check all of them for you, so why try to check all the recently added ones for you and check them daily.
I'm looking into some optimizations concerning this, that may allow me to drastically improve the performance of our domain checking (which already is pretty fast).
So if you are looking at a keyword, to make sure you have the latest data concerning the domain names, push the "Check Domains" button, and that will check those domains if they haven't been checked today.
It's hard to be perfect, but our goal is to be accurate, and I thing we don't do too bad

We'll keep improving the service to make it better and better for you guys.
Hope this explains it better to you. Wish you the best of luck.
