TL;DR - My unofficial mirror of the Silverblue ostree content is going to be shut down on 2019-Sep-5
Back in March of 2018, I setup an unofficial mirror of the Silverblue ostree content in response to complaints of slow upgrade speeds for users outside the US.
Since then, there have been drastic improvements to the infrastructure distributing Fedora ostree content and most of the complaints about poor upgrade speeds have stopped.
My unofficial mirror never picked up the F30 Silverblue content and soon F31 will be available, so it seems like a good time to retire this service.
If you happen to still be using the unofficial mirror, I urge you to use the official Fedora remote for Silverblue.
