When a wiki is deleted, it appears there is a set time for which that wiki is considered "recently deleted", and after that time the wiki becomes "deleted". I tried to make a new wiki using a recently deleted wiki's URL, but it said that there was an existing wiki with that URL. I've made a wiki with a deleted wiki's URL before, so I know that it's possible.
What is that set time when a wiki goes from "recently deleted" to "deleted"?
