It did not show any history for the domain I know had expired.
Was it a website or just an expired domain?
Also it does not include my 1 year old site.
Right now there is a 6-12 month lag between the date a site is crawled and the date it appears in the Wayback Machine. Also, there are various other reasons sites don't appear in the archive. You can get more info in their FAQ.
