Hi people

Been trying to figure this out and it is a headache as i cant get some indication on what will happen.

if my site was around since 2001 and has been redirecting with a 301 to another site for the past 3 years, the i decide to make it live again, what will happen in terms of the age factor of the domain?

does google still treat it as a domain from 2001?

or will it have lost all its power from the redirect?
