The advantage of SMS is that it is out of band. Any smtp or other IP based solution requires a stable and working network environment, which is what the alert may be trying to tell you is down. ---- Matthew Huff | 1 Manhattanville Rd Director of Operations | Purchase, NY 10577 OTA Management LLC | Phone: 914-460-4039 aim: matthewbhuff | Fax: 914-694-5669 -----Original Message----- From: NANOG [mailto:nanog-bounces@nanog.org] On Behalf Of Thijs Stuurman Sent: Friday, November 21, 2014 10:52 AM To: nanog@nanog.org Subject: Incident notification Nanog list members, I was looking at some statistic and noticed we are sending out a massive amount of SMS messages from our monitoring systems. This left me wondering if there isn't a better (and cheaper) alternative to this, something just as reliant but IP based. We all have smartphones these days anyway. Therefore my question, what are you using to notify admins of incidents?
