Well I'm looking at a domain that was last registered on 22th Feb 2011, status is expired, last modified date on whois is March 8th 2013.
So it must have expired on Feb 22th this year. Not sure what happened on March 8th, but am trying to work out when it will be hitting the drops.
I can't really do much until it drops anyway, was more curious if there was a strict timeline I can work with.
