service-template-node exists.
https://github.com/wikimedia/service-template-node/issues also exists.

https://www.mediawiki.org/wiki/ServiceTemplateNode does not provide any information where to report issues, nor does the GitHub README.

Either the Phabricator project should be archived, or Github settings should be changed not to allow issues.

Apart from encouraging conversation fragmentation, duplication, and wasting time and efforts there aren't many good reasons to have two issue tracker locations.
