The backstory goes that WordPress 4.4 introduced the `WP_Network` class (see: #31985) and with it came a simple new method for getting a network, aptly titled `get_instance()`. This method is used in `ms-settings.php` and `ms-load.php` in place of some previously duplicated and uncached code, and is used to retrieve a network's details from the `wp_sites` database table. That query is wrapped in a new cache check with a new `networks` cache group, but this group was never added to the global cache groups array. It's not a regression, but it could be slipped into 4.4.1 as it was an unintentional oversight that could cause cache corruption in multi-network setups." defect (bug) closed normal 4.4.2 Networks and Sites 4.4 normal fixed needs-patch good-first-bug multisite
