let me get it clear: 1. a home page of site is deindexed from google temporertely. so ranking all gone. 2. site got lost from google or down for only 2-5 days and back to normal even better. list goning. plz you?
It is not sandbox in both cases. Probably you have build a lot of links or created too much pages in short time. If this is you case don´t worry about your ranking, you will be back shortly.
