[CentOS-mirror] Corrupt ISO images?

Hi List,

I've received a report of corrupt ISO images on our mirror server, ftp.heanet.ie:/pub/:

centos/4/isos/alpha/centos-4.3-alpha-disc1.iso centos/4/isos/alpha/centos-4.3-alpha-disc2.iso centos/4/isos/alpha/centos-4.3-alpha-disc3.iso centos/4/isos/alpha/centos-4.3-alpha-disc4.iso

I've verified that the ISO images do not match their expected MD5 sums, and re-tried downloading them all from the repository we sync from (eu-msync.centos.org::CentOS/), but the ISO's appear to be corrupt there.

Is this a known issue? Is there a procedure or contact point I can use to talk to someone about this?

Thanks! Brian.
