For many years, the Dreamhack service was managed and maintained by Sophie. As a Perl coder and systems administrator, Sophie used to maintain a similar, privately-run service for Goathacks (ready-to-go LiveJournal installs) after the original Goathack service died. Dreamwidth is very thankful for her years of contributions!
Credit must also be given to Afuna for running the first Dreamhack service. Thanks, Afuna!
