I will be moving servers for the down.nu domain today (23rd of Sept) at 8PM UTC. In theory this should be a smooth transfer, but be aware that you might encounter some issues.

I'm also still offering the possibility to centrally host LibreELEC images if anyone is actively working on it, so that we can provide an automatic update function like with OpenELEC

Move is completed and don't see any errors popping up. For me it's working fine.

Dns update can take up to 48h, so I will keep the old server alive as fallback for those on slow DNS servers
People on OpenDNS and GoogleDNS will already be on the new server.

Please report back if you encounter any issues downloading files and/or updating.
