Dillo’s domain name has expired, making it impossible to fetch its Mercurial repository from its canonical location. Fortunately, Mercurial is a distributed version control system, and I had a copy. I pushed my copy to hg.sr.ht; you can see it there.

The Wayback Machine also has recent snapshots of dillo.org from May.

I imagine that at least a few people have copies of the mailing list archives.
