Archive.org appears to have a good portion of the list archives
mirrored as well (although it looks like around 2019 the index page
was changed to hide the month/year links):

Unfortunately, since it's just a static mirror, some of the features
such as search aren't able to function.
They would also likely be able to host an export of all posts if it
can be generated.
