Postmortem: INC198965 – e-Transfer 3.4 and 3.5 Brief Outage
On Wednesday, April 9th, Central 1 experienced a brief disruption impacting e-Transfer services between 12:50 and 12:54 p.m. PT (3:50 to 3:54 p.m. ET). Services recovered automatically without requiring intervention.
Our UCP system was temporarily unable to communicate with Interac through our Vancouver (VAHC) network connection. Despite this, the UCP system remained responsive throughout the incident, and Interac confirmed they observed no issues on their end. The incident was escalated to our Network team for a deeper review of underlying network-layer activity.
Root cause analysis: Further investigation by our Network team determined that a firewall error briefly disrupted connectivity between UCP and Interac. The firewall rule was quickly corrected, restoring full service.
As part of our corrective actions, we are enhancing our network-layer logging to improve visibility and speed up future investigations should similar events occur. Central 1 remains committed to maintaining reliable service and strengthening our diagnostic capabilities.
