We can confirm being hit by
27.221.66.0/24 pulling the same iso as well. What
action was taken to address this by your networks?

Have you noticed that in your mirrors? look for these IP
and notice if they have been trying to continously
download iso
We did encounter the same issues with the same IP
addresses and same iso file. Till now I thought it was
an isolated issue..
