Several minutes after midnight on October 30th, 2007 we completed all primary burnins of new ExchangeDefender inbound systems and went live. The DNS updates can take (at times several days) to be recognized by some name servers so the impact should be negligible. The network and analytics are running at the fraction of network capacity but with constant product feature evolution comes contstant upgrade.

As mentioned earlier, the reason for the upgrade is simply to increase the brute force of the ExchangeDefender security perimeter. With the changing scope of junk mail and threatening content being sent to compromise or damage systems, we are arming up for the problems we see on the horizon.
