Unfortunately I don't have an account at CERN (at least that I'm aware
of) so reproducing this could be tricky. However we have been able to
submit jobs via the CERN RB which fail to get anywhere just like the SFT.

Since my original reply we've seen the same error messages
following connections from non CERN sites as well.
The error messages on our server started about 4:35 yesterday which
was about half an hour after we updated the LCG software on the
cluster to the latest revisions (including rerunning YAIM). It appears
the 4-5 earlier SFT runs that failed had different causes.
Network connections seem to be OK (at least in this direction)
tcptraceroute grdb03.cern.ch 7772 from my desktop (firewalling plus the
absence of a tcp based version of traceroute prevents me from doing this
from our CE):

Not quite sure why it repeats the gdrb03.cern.ch 4 times but it gets there.
