Postmortem - ### **Incident Summary** On Tuesday, May 27, 2025, at approximately 11:14 AM ET, CallHarbor began receiving reports of one-way audio on some calls originating from or terminating through our Detroit Point of Presence (PoP). Our team was able to reproduce the issue through internal testing. Following reproduction of the issue the CallHarbor team initiated a failover to our other Points of Presence to mitigate any impact. While this did resolve the issue some clients may have had a brief period of one way audio on calls between approximately 11:14AM ET to 11:30AM ET provided that their calls traversed our Detroit, MI PoP. We sincerely apologize for any inconvenience or disruption this incident may have caused to your communications. We understand the critical nature of reliable audio for your business operations. ### **Timeline of Events** **Initial reports and resolution put in place:** * **11:14-11:18 AM ET:** Initial reports of one-way audio through Detroit, MI PoP received by CallHarbor Support. * **11:19 AM ET:** Network engineers engaged to begin verification of issue. * **11:20 AM ET:** Internal testing confirmed the one-way audio issue. * **11:25 AM ET:** Decision made to initiate failover of services from Detroit to our Atlanta and Phoenix PoPs. * **11:28 AM ET:** Failover initiated. Devices began successfully re-registering at the Atlanta and Phoenix PoPs. **Investigation and Restoration of Detroit, MI PoP:** * **11:32 AM ET:** Status page updated outlining steps taken and that issue has been identified. * **11:32 AM ET - 8:30 PM ET:** Investigation into the cause of the one-way audio during failover. All CallHarbor-managed equipment and services in Detroit were confirmed to be online and stable, indicating an external factor. * **9:00 PM ET:** Failback to the Detroit PoP commenced. * **9:06 PM ET:** Services in Detroit were fully restored with two-way audio confirmed, and no further issues were observed. ### **Root Cause** Our investigation determined that the one-way audio incident was not caused by any CallHarbor internal systems or equipment. All CallHarbor infrastructure in our Detroit PoP remained stable and operational throughout the incident. The issue has been attributed to a connectivity problem with an upstream carrier providing service to our Detroit PoP. This upstream issue prevented the proper flow of audio in one direction for some calls. ### **Resolution** The immediate resolution involved a successful failover of services to our geographically diverse Atlanta and Phoenix PoPs. This proactive measure ensured minimal service disruption for our customers, allowing calls to be routed through unaffected infrastructure. Once the upstream carrier issue appeared to be resolved or mitigated, a controlled failback to the Detroit PoP was executed without incident. ### **Future Prevention and Resiliency** While we do not anticipate a recurrence of this specific upstream carrier issue, this incident underscores the critical importance of our multi-point of presence architecture. This design, combined with our relationships with multiple upstream carriers, provides significant resilience against external outages. Our ability to quickly failover to alternative PoPs demonstrates our commitment to maintaining high availability and reliable service, even when faced with issues outside of our direct control. We will continue to monitor our carrier connections closely and explore further diversification where appropriate..

Monitoring - CallHarbor is reopening this incident as we are beginning to see increased latency, and post dial delay on inbound calls. We are currently not seeing call failures, however we are continuing to monitor the situation. The upstream carrier has not released any updated information today at this current time. -- Our primary upstream carrier for inbound calling and inbound and outbound messaging on the PSTN is currently experiencing an attack on its network. Many if not most of the United States largest VoIP and cellular providers utilize this upstream carrier to provide connections for voice inbound and outbound. Due to the way that telephone numbers work, we cannot set up a failover in the event that our main upstream carrier experiences an attack. We selected our upstream carrier based on multiple decades of great service and uptime, this is also why many of the other VoIP and cellular providers as well as largest organizations on the planet have chosen them. Outbound calling can support failover and all of CallHarbor's outbound calling traffic has been migrated away from this upstream carrier who is experiencing an attack. As the attack is ongoing there may be periods of poor audio quality inbound, or inbound call failures. If you are experiencing an issue inbound or outbound do not hesitate to reach out to CallHarbor we are here to help, we are still looking through all poor audio or call issues to determine cause and resolve where possible. In the event that the issue is caused by this upstream carrier attack we will inform you. We are working with our other major carrier partnerships to build a plan in the event that this attack on this major carrier appears to extend in time. This would take some time to implement (due to porting restraints nationally) however we are prepared to protect you and your business. CallHarbor is currently having no issues with its own network, or extension to extension calling; Furthermore some CallHarbor customers do not rely on this upstream carrier for service and will be unaffected by this attack. If you are having trouble reaching CallHarbor support through our main line you may dial our alternative support line: 313-644-7500 We will continue to provide updates at https://status.callharbor.com in order to be as transparent as possible regarding the current issue affecting VoIP providers nationally.

Identified - Our primary carrier for inbound calling and inbound and outbound messaging is currently experiencing a partial service outage impairing inbound calling as well as inbound and outbound messaging. Not call customers may be affected by this partial service impairment as not all customers operate through this carrier. Outbound calling should be unaffected as we have multiple carriers in place for outbound calls. Due to the fact that inbound numbers may only be with one carrier it is currently not possible for CallHarbor to migrate numbers instantly or to provide full failover in the event of a major carrier issue. To reach CallHarbor support you may dial: 313-644-7500.
