If you can read this, the problems have probably been fixed,
but I'm having DNS problems contacting scientificlinux.org

# host ftp.scientificlinux.org
Host ftp.scientificlinux.org not found: 2(SERVFAIL)

# host linux21.fnal.gov.
;; connection timed out; no servers could be reached

(I can still get response from home. Either the cached entries
haven't timed out yet or the dnssec on the work DNS isn't helping.)
