Connectivity issues

On 15 July 2026 at 12:01 PM, our Brisbane datacentre facility undertook scheduled power works requiring the shutdown of a single power rail feeding all racks. All TechPath equipment is dual power supply, fed from independent A and B power rails, and this work was not expected to cause any service impact.

During the works, a suspected voltage sag occurred on the secondary (remaining) power feed - similar to a brownout condition. This caused interfaces on some network hardware to reset. As a result, network paths dropped, including within redundant topologies, until links renegotiated and stabilised. Logs confirmed interfaces flapped multiple times as the facility shifted power loads during the works.

The repeated link transitions caused one of our SD-WAN aggregation nodes to go offline and enter an inconsistent state. Because links were transitioning in quick succession, the SD-WAN controller was unable to reliably confirm the state of the node. Manual verification was required, and affected customer services were migrated to alternative aggregation points to restore connectivity. Restoration of some services took longer than desired; however, this time was necessary to ensure no impact to other customers and services.

TechPath engineers were onsite at the facility within 30 minutes of monitoring alarms. Facility staff advised they were not aware of any voltage sags; however, other providers onsite at the time experienced similar issues and were also investigating.

We have escalated this event to our SD-WAN platform vendor for review, specifically to determine what improvements can be made for automatic recovery should a similar sequence of events occur again.

The facility completed the power works at approximately 4:00 PM, at which time full power redundancy was restored to all racks. Network monitoring confirmed the power restoration occurred without incident, with no further interface resets or service impacts observed.

We apologise for the disruption caused and are continuing to work with our vendors to bolster service resilience. No further updates will be provided on this matter.

TechPath engineers have identified the issue and have made changes to get any impacted clients back online. At this point, all services are restored.

TechPath is currently investigating connectivity issues affecting some clients.
Updates to be provided shortly.
