What you describe sounds perhaps like a DNS timeout (which
SA3 may support through your operating system's resolver).
There are currently three SURBL nameservers with problems,
but they're all commented out of the authority for the
subdomains, so they should not be a problem.

If you do:

  dig test.surbl.org.multi.surbl.org a

many times, do you get any delays?

Is anyone else seeing problems?
