The dnsbl always seemed reachable even in the middle of the ddos'es, 
although their web pages frequently were not. They were timing out on me 
though.

For future reference, add the line "options timeout:10" to the file 
/etc/resolv.conf and restart sendmail. The 10 is in seconds. the default is 
5. SPEWS started responding when I upped to 10.  dnsbl's are treated as dns 
servers.
