Hello,

we shutdown our mirror for maintance Operation.

Mirror: http://mirror.418grad.media/centos

I'll inform as soon as Mirror is online again.

OK, I've marked your server as gone in the meantime. If the mirror comes back to life some day, you may need to do an initial sync (or a refresh sync) from some other external mirror first, because mirrors marked as gone can't use msync.centos.org as their source.
