From the license (https://www.gnu.org/licenses/agpl-3.0.en.html https://www.gnu.org/licenses/agpl-3.0.en.html): Notwithstanding any other provision of this License, if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge, through some standard or customary means of facilitating copying of software. This Corresponding Source shall include the Corresponding Source for any work covered by version 3 of the GNU General Public License that is incorporated pursuant to the following paragraph Sounds to me like the 'all users interacting with it remotely through a computer network' part doesn't distinguish between an internal service and an external service. If it has users, you must comply with the license. I'm not a lawyer, this isn't legal advice.
