>Description:
The Content-Type header reported for ISO files hosted on archive.netbsd.org is wrongly reported as "text/plain" (ISO files are definitely not a text format). On cdn.netbsd.org, ISO files have "application/octet-stream" as Content-Type, which is a bit generic, but still OK.

This can be seen e.g. with curl (trying with two random ISOs, one on cdn.netbsd.org and the other on archive.netbsd.org):

$ curl --head -L 'https://cdn.netbsd.org/pub/NetBSD/NetBSD-9.0/amd64/installation/cdrom/boot.iso'
