When does .com/.net/.org domain become available if it not renewed.
The deletions are preformed by Verisign Global Registry Services, and they do not publish a timetable of when they delete domains i’m afraid.
If the domain you’re asking about is not renewed within the 40 day normal expiry period, it goes into the 30 day redemption period and then the 5 day deletion process. 75 days generally from the date of expiry to availability.
