Note: sending this from my personal account to increase odds of someone seeing it. My work address is dmahoney@isc.org. ISC is having trouble mailing noc@level3.net, we keep getting redirected to a messagelabs error, seems to be happening from any address we send from, including personal addresses and the (sender/envelope) address of our ticket system. This is probably nonoptimal. You can reach me voice at 650-423-1362, or our noc number at 650-423-1310.
