SignalWire experienced an outage earlier this morning. Their status site post is here: https://status.signalwire.com/incidents/MJVYwKKYYwbG Our first customer report of problems was at 1:51 AM PST (09:51 UTC). During the incident, many SignalWire SIP calls were returning 603 Declined. As we were investigating, SignalWire opened an incident on their status site at 2:26 AM PST (10:26 UTC). Their incident post didn't provide enough information for us to determine the overall impact to our customers. As we continued investigating our own logs and pressing SignalWire for more information, our affected customers started reporting that the issue was resolved around 2:35 AM PST. SignalWire ultimately resolved their incident at 03:27 PST.
