Trying yesterday to do a yum update, it stopped midway through
downloading headers and I had to force quit.

Since then when I try to do an update I get

$ sudo yum update
Gathering header information file(s) from server(s)
Server: DAG rpms
retrygrab() failed for:
 
ftp://ftp.scientificlinux.org/linux/extra/dag/redhat/el3/en/i386/dag/headers/header.info
  Executing failover method
failover: out of servers to try
Error getting file
ftp://ftp.scientificlinux.org/linux/extra/dag/redhat/el3/en/i386/dag/headers/header.info
[Errno 4] IOError: [Errno ftp error] (110, 'Connection timed out')

Is there a problem on the scientificlinux.org end, or is there something
screwed up on my end?
