Oh, yeah, I see what you mean. Yes, it could have affected updates, but I’ve checked and software.virtualmin.com is resolving correctly on the new DNS servers. So there should be not outage for existing systems.
That said, for anyone who installed using the new install script with the new download.virtualmin.com repo, there may be an outage as we’re also putting a CDN in front of it (Our Websites Might Get Weird). software.virtualmin.com is still on the old server, and not getting a CDN, so it’s definitely not breaking (at least not because of anything we’re doing).
