FWIW there was a brief error where .com got into ab.surbl.org and that caused it to hit all .com domains. This problem lasted an hour or two today and happened between around 01:00 to 0:300 UTC on 5 May 2005. Andy's fixed the data side of AB, and I've added dotted and non-dotted versions of all gtlds and cctlds to the SURBL whitelist to prevent these from getting listed. Source for the cctld list is the standard ARIN page:
