I have several CentOS 8 machines that I update and every now and again I
will go through and update all of them and one of them will get a slow mirror, like downloading the kernel at 50kb etc. With the newer version I
am unable to figure out how to force it to update the mirror list and hopefully change to a faster mirror. I have searched but must not be using the right verbiage since I am unable to find the easy solution to dump the mirrors and re-select.

Thanks :)
