Between approximately 09:00 and 12:30 AEST today, customers experienced call delays and app registration failures. Service has been restored.
What happened
A botnet attack originating from a legitimate wholesale customer generated a large volume of malicious traffic, overwhelming our infrastructure — including our website, app, and handset registration services.
Resolution
We identified the source quickly but were slow to escalate and isolate the customer's traffic via our WAF and firewall rules; the surge should have been quarantined as soon as it was detected. We've since updated our automated traffic defences to prevent a recurrence.
Apology
We apologise for the disruption. If you're still experiencing push notification registration issues, please contact support and reference 22-Jul-2026.
