lug.mtu.edu was removed from the mirrors list. (see bug #63651). ISO downloads are allowed from local area address only, but all other files should be publically available. Please re-list, perhaps as a partial mirror?
Peter, Just checked this, looks like ISO downloads are allowed from anywhere. I'd prefer if you're going to restrict downloads on the mirror, you could sync from somewhere other than masterdistfiles.gentoo.org since all the users cant take advantadge of it. Let me know and I can add you accordingly. Thanks, Jeff
Peter, Sorry about the long response, I've finally added you guys back into the mirror listing. Thanks! -Jeffrey
