# This periodically restarts the Matrix services
# to ensure they're using the latest SSL certificate
# in case it got renewed by the `ssl-certificate-renewal` cronjob
# (which happens once every ~2-3 months).
#
# Because `matrix-nginx-proxy.service` depends on `matrix-synapse.service`,
# both would be restarted.
