I've been running fedora.is for many, many years at Siminn.    We are now currently moving it to a new server at a new location.
the IPv4 and IPv6 addresses will change.  The name (fedora.is) will not change, but I do like the hostname of the new mirror server, which is mirrors.opensource.is :)

What are the ACL and/or mirror-manager changes I need to go through to get this done?

Best regards,
