One of our SBC AWS instance in Singapour (region ap-southeast-1) has become unreachable in a unusual way. Neither reboot, shutdown nor terminate would work on the instance. We have opened a ticket with AWS waiting for an answer.
The elastic IP address 52.220.255.72 (sg1.sip.callr.com, asia.sip.callr.com) has been reassigned to a backup instance, and the platform has ben re-configured to route calls through this instance.
We are waiting for an explanation of this bug from AWS, since their status page shows no outage at this time.
