[Resolved] Continued TFN Inbound Issues

Began: Ended: Duration:

We've received reports of continued TFN inbound issues. We will continue to monitor.

The core of the issue has been identified and it is not native to the Plum Voice infrastructure. A distributed denial-of-service (DDOS) attack is impacting a major carrier within the telecom space.

We are continuing to monitor the situation. Thank you.

We are receiving early indications that normal functionality has been restored. We are continuing to monitor for signs of additional health.

Our partner carrier has engaged remediation experts to prevent additional attacks from re-occuring. We have not experienced any additional issues but we continuing to monitor as this incident continues.

All issues are reported as being resolved and DDoS mitigation remediation has been successful. We are continuing to monitor the situation before formally flagging this as resolved.

DDoS remediation is currently underway as another wave of DDoS attacks has taken effect. The potential for failed calls exist and we are monitoring the situation.

Remediation steps have proven effective. Note: calls will complete with degraded voice quality.

Calls are connecting as expected. There is continued degradation in audio call quality.

Call quality issues persist alongside a certain percentage of calls not connecting. Issues are intermittent and we continue to test and monitor.

We are continually testing and monitoring. At this time, we are experiencing ~ 20% call failure.

Our team is continuing to test and follow along with all current issues. Migration of services to prevent further DDoS attacks is still underway. At this time it is possible to experience failed calls or degraded audio quality until the migration is finalized and issues are completely resolved. We appreciate your patience and understanding.

Remediation steps are still underway and additional steps have been taken to improve audio quality. We are continuing to monitor.

All internal testing points to the DDoS remediation attempts as being successful. We are continuing to test and monitor until the final all clear is given. No observable impairments are occurring at this time.

Current testing indicates that a portion of calls are not being completed. This is potentially an extension of previous waves of DDoS attacks.

Plum Voice infrastructure and applications are functioning normally. All DDoS attacks are not native to our platform. These attacks are limited to certain carriers and prevent calls from being passed through to the Plum Voice platform. Testing and monitoring are still underway.

We've received word that all impacted carriers have resolved issues stemming from a previous DDoS attack. At this time we are monitoring from our end to help ensure no additional service disruption is present. We are leaving this incident open but in a recovering status as there are no observable impairments at this time.

We've received alerts of call quality and connection issues. Certain calls are not connecting. Other calls exhibit degraded audio quality. These symptoms are in line with previous DDoS attacks. Additional context on these attacks can be found here:

We appreciate your patience and understanding.

Audio quality has increased. Calls are connecting successfully.

We are observing a restoration of normal call connections and audio quality. We are continuing to monitor for changes.

DDoS attacks are actively being mitigated outside of the Plum Voice network. No discernible service impairments are present. This information is being provided as a precaution and we are continuing to monitor system performance.

Monitoring has alerted us to intermittent issues affecting PCI TFN numbers. This is currently escalated and already under review with our vendors. Thank you for your patience while this is being investigated further.

Our team is seeing service restored to normal. All testing is successful and monitoring has cleared. We are continuing to monitor further at this time.

We are currently observing intermittent call failures on toll-free PCI and non-PCI numbers. Our team is investigating and escalating with the appropriate resources. We appreciate your patience as we continue to look into this. Please direct any and all questions to support@plumvoice.com. Thank you.

A renewed DDoS attack on a major telecom vendor is actively being mitigated by the telecom vendor's team. We are monitoring the situation.
