Relizon Canada Inc.’s AS 40034 RELIZON-CDN jumped from #134 to #3 in the May 2013 for Canada All from CBL data. On May Day CBL saw 1 spam message from AS 40034 and more than 3 million on May 31.
Relizon was not visible in the May Canada rankings from PSBL data, although internally we do see AS 40034 going from #208 to #109 by going from 11 spam messages in April to 26 in May. CBL’s heuristics or spam traps or both were apparently much better at detecting this particular spam source.
Relizon’s own website doesn’t seem to be responding at the moment, but Bloomberg Businessweek says they do business process outsourcing solutions, and were formerly known as Crain-Drummond Inc., with the name change coming on acquisition by the Carlyle Group.
