If one looks at the Stack Exchange site index list, one can observe that the Sound Design site (which is apparently in beta, by the icon), has a site age of 2012 years and 8 months. (The site creation date, as a timestamp, is -62135596800.)
If you click the link on the index, it goes correctly to the Sound Design SE, but if you click on the Area 51 link, it's not found. A search of Area 51 turns up only unrelated results as well.
I believe this is because it was (just) upgraded to a SE 2.0 site. While it's impressive that this SE predates the Internet, this should probably still be corrected.
