In the late 1950s, the Minnesota Department of Transportation used eminent domain to clear the path for I-94, displacing over 700 families and 300 businesses in Rondo, a predominantly African-American neighborhood. In the 2010s, Rondo residents and faculty at Macalester College teamed up to create Remembering Rondo, a digital public history project that included (among other things) a community-based archive and map of the neighborhood’s historic businesses from 1920 to 1960. Rondo Avenue, Inc., the neighborhood’s community council, asked to host the project themselves. Then in 2020, they forgot to renew the domain. The site went dark. This essay explores where we went wrong and what we can do about it, and raises questions about how we can reimagine digital sustainability through the lens of a shared authority.
