i am the sys admin of the centos mirror at ftp.iitm.ac.in; i sync from us-msync.centos.org. in the last 2-3 weeks, i seem to be having a problem with the 5.1 directory - it keeps flip flopping between empty (but for the readme file) and fully populated (os, extras, updates etc etc) - downloading and deleting a couple of gb every time. i randomly checked a few mirros and this seems to be widespread. what gives? -- sriram
