Upgrading systemd drops net connection for a short while

[john doe <johndoe65534@mail.com>]

Hi, while upgrading the following three packages my internet connection
drops for a short while:

libpam-systemd (232-25+deb9u9 => 232-25+deb9u11)
libsystemd0 (232-25+deb9u9 => 232-25+deb9u11)
systemd (232-25+deb9u9 => 232-25+deb9u11)


I'm using Systemd for dns and interface configuration on Stretch.

Has anyone seen this?
