Monitoring
We identified elevated outbound telephony (SMS and voice) failure rates between 7:38 AM and 8:14 AM Eastern on 2016-09-26. We believe the failures were related to an Amazon Web Services networking issue affecting a subset of our multiple telephony providers. The issue appears to have subsided and we are continuing to monitor for additional failures.
