What's the deal with Deno? We talk with a major contributor to find out. Listen now.

Found the cause. I'm using a third party tool to manage, upgrade and monitor my Joomla sites. One of the features is to scan the site for available updates, during this process the update sites are all enabled. The developer confirmed this was the expected behaviour of the product. I'm able to disable this feature and my updates sites now remain disabled.
