package management - Does the old version of apt information file exist on the website?

When I execute apt update, apt will update the file on the website listed in /etc/apt/sources.list to local, for example, http://cn.archive.ubuntu.com/ubuntu/dists/xenial/main/binary-amd64/Packages.gz, apt update will download this file to local(/var/lib/apt/lists). this file describes the dependencies of the deb package.

Does the old version of this file exist on the website?

Thanks in advance!
