Comment 7 for bug 1628302

We're not seeing this error anymore, after using ipv6 enabled specific mirror with change[1]. However as discussed in the team meeting, we need a better long term solution i.e local mirroring or avoid downloading images completely(at present 2 tests need the downloaded fedora image) .
