What details do you want?
It's a brand new install with literally no changes and it can't download from the mirror list. I have logs now from a new install, which again does exactly the same thing.
It's timing out reaching the mirror sites. I have tried manually curling some of them and the download starts, seems to get most of it downloaded then just hangs.
I have a CentOS 7 machine with a fresh install on the exact same network that works fine.
