Greenbone feed mirrors?

The “official” feeds seem to always be blocking. Are there mirrors that can be configured instead? I need to reliably update the feeds without getting blocked all the time, even when I haven’t tried to update for days.

I’d be happy to host mirrors if that’s a thing.

If there are no mirrors, why not? Is this an open source project, or an “open source but commercial” project?

I found this repository on Github that hosts GVM’s plugins. Haven’t checked if it is the full feed or not.
