   Summary / Impact

   On the afternoon of May 31st, 2026, 14IP's network operations group began to observe connectivity issues with resources located at its US-Central (MKE) data center.  The team began working with their counterparts at the data center facility to understand the nature of the problem.  It was quickly determined that a distributed denial of service (DDoS) attack targeted upstream was affecting all tenants of the data center.

   Significant malicious traffic (exceeding 450gbps) was measured upstream during the peak of the attack which overwhelmed equipment as well as primary, secondary, and tertiary links.  This traffic was mitigated through coordinated, escalating filtering with upstream transit providers, as well as internal engineering to stabilize routing.

   During the incident, connectivity to systems and services primarily located in this data center were impacted significantly for periods of time between approximately 2 PM ET and 9:30 PM ET.  This included Clearly Cloud, ComXchange hosted, Xivea, Business Connect, EPlatform, and several other systems.  (US-East trunking services continued to operate during the US-Central incident.)

   Follow-Up

   Several facility-level network and system improvements have been implemented following the incident which should reduce the risk of future occurrences.  This includes the deployment of additional DDoS scrubbing capacity, improved granularity for detecting attacks, additional fiber capacity upstream, as well as core network enhancements.

   14IP plans additional improvements to its systems and operations to improve platform resilience and flexibility when responding to future incidents.

   At approximately 11:27AM ET on November 3, ClearlyIP's NOC team began to receive system alerts indicating excess session activity within its US-East trunking systems. The team's investigation identified unauthenticated INVITE messages being received from unknown IPs as the source of the excess traffic, as well as a customer generating unexpected levels of outbound calls. Steps were taken to mitigate the traffic's impact, including restarting affected services to clear sessions and restore normal status. By approximately 11:55AM ET, the US-East situation was stabilized and session traffic had returned to normal levels. The team has identified a number of improvements and traffic management strategies to help avoid similar incidents which will be implemented in future maintenance events.

   At approximately 4:10 PM ET, ClearlyIP's monitoring systems detected registration issues within US-Central trunking. Within a few minutes, it was determined that one of the two primary trunking servers was maintaining its active calls \(2.us-central\) and that its counterpart \(1.us-central\) had stalled and was not accepting traffic. It was quickly determined that the issue stemmed from a database cluster deadlock within the US-Central footprint. Upon analysis, the deadlock's cause was identified to be related to unsuccessful credential change activity. A series of actions were taken during the next 30 minutes which restored 2.us-central to service. Following that, maintenance was performed to resolve version differences on the database node not currently in production before restoring it \(and 1.us-central\) to normal service shortly after 6PM ET.

   A scheduled data center facility network maintenance event occurred during the evening of 10/29, which caused a variety of anticipated monitoring alarms during its completion. The data center facility provided expected updates on the maintenance activity and no issues were immediately noted following its conclusion. At approximately 8AM ET on 10/30, a customer reported that trunk registrations to the ClearlyIP US-East trunking servers were failing, while US-Central trunks were operating normally. The issue was escalated by support to engineering, as it indicated potential issues with inbound calling mapped to the US-East region and would also affect customers who hadn't configured redundancy with ClearlyIP US-Central trunking. After analysis, some database connectivity issues within the affected data center were identified as likely to be responsible. The engineering team conducted a full review of the affected equipment and began work to restore access to the unresponsive database servers. This required a careful review of replication and synchronization states before steps to re-activate each of the affected servers were taken. By approximately 8:45 AM ET, the team had determined data integrity was intact and started operations to restore synchronization between the US-East database notes. At approximately 9 AM ET, US-East trunking servers were reopened to customer traffic. Systems monitoring and review occurred immediately following US-East reactivation, and support teams were advised to monitor customer equipment for proper re-registration with US-East servers. During final analysis, several process and monitoring improvements were identified for implementation which should help avoid similar monitoring ambiguity \(and potential disruption\) during service provider maintenance events.

   At approximately 2:30 PM ET on October 29, alerts began to be received by ClearlyIP's Network Operations team indicating problems accessing the database cluster used by Clearly Cloud for most US-based customers. This was interfering with call routing for a portion of customers and prevented access to Call Panel and other system components. The team immediately began investigating and observed the problem related to a protective mechanism which had detected large amounts of database request traffic and proactively restarted services to prevent data loss or corruption. The source of the requests was quickly identified, stopped, and determined to be legitimate. The team then checked each server in the cluster before determining it was safe to restore normal service by approximately 2:45 PM ET. A postmortem analysis on the source of the database traffic identified it to be related to delivering an unusual backlog of SMS and email messages from the platform. Temporary measures were taken to prevent a recurrence of the same issue while long-term improvements are scheduled.

   On 9/16 at approximately 1:50 PM CDT, ClearlyIP began to receive indications of connectivity problems affecting the Pulsar360 Denver data center. Infrastructure and network teams were immediately notified and began troubleshooting. The team quickly ruled out internal infrastructure issues, confirming that links to all Pulsar360 equipment were working normally. Within 15 minutes, the team had identified the source of the issue as a regional Internet routing problem caused by actions of an unrelated third-party fiber provider. The issue originated within a route \(BGP\) advertisement that erroneously included large sections of IP addresses--among them addresses used by Pulsar360's Denver location. That bad route information caused many ISPs to misdirect traffic away from the Denver data center location. ClearlyIP's engineering team pursued parallel efforts to resolve the underlying issue and explore workarounds that could be executed more rapidly. While contact was still being made with the third-party company through upstream contacts, a solution involving forced advertisement of smaller network segments \(counteracting the large mis-advertisement\) was tested successfully. The approach was approved quickly and the team immediately began executing it for all of the Pulsar360 Denver network segments during the next 30 minutes, restoring connectivity. Stable connectivity had been achieved across the entire Denver network approximately one hour after the incident had been reported.

   At approximately 6:18 PM ET, an internal alarm detected a component restart within the Clearly Cloud US platform. The engineering team quickly determined that the component successfully failed over to a redundant system while restarting, but this resulted in a few moments of disruption for dialing and status notifications \(BLF, MWI, etc.\) The issue was immediately escalated to key members of the infrastructure and software groups who were conferenced in to analyze the situation. Approximately ten minutes later, another restart \(and failover\) occurred, causing another brief disruption to new calls and status updates. The team identified the issue to be triggered by data integrity problems with several contact records. Research confirmed that this issue had never been encountered before, occurring while a routine system task purges expired contact records every 10 minutes. Several solutions were explored, and ultimately a repair of the affected data table was performed at approximately 7:40 PM ET, resolving the underlying problem. Additional cleanup tasks were implemented at approximately 8:00 PM as the escalation team monitored the platform. After recording several task cycles without further incident, the team reviewed potential improvements and documented the incident before marking it resolved at approximately 8:15 PM ET. While every part of Clearly Cloud has redundancies and most of these fail over gracefully without impacting operations, the component in question requires a few moments for backup systems to take over. During this timeframe--between a few seconds and a minute--established calls would be unaffected, but new calls may fail to complete and status messages for BLF, MWI, parking, and other notifications may fail to be sent. Although the issue's impact was limited due to the time of day, multiple brief failovers in a short timeframe caused disruption, which was noticed by several users ClearlyIP's engineering team will incorporate what was learned about this incident within upcoming platform improvements.

   During the early afternoon of Friday May 16, our engineering team detected a potential issue and proactively moved production SIP services onto a secondary redundancy system in an abundance of caution in order to prevent a widespread service disruption. For approximately an hour, the secondary system operated with limited BLF functionality but processed calls and registrations normally. There may have been very brief issues with call setup or registration during the failover and failback process. BLF features were restored to normal functionality at the conclusion of the failback operation.

   During the morning of Wednesday May 14, we began receiving reports of intermittent issues from Clearly Cloud users in parts of the US with registrations and call completion. The engineering team immediately began investigating and closely monitored the performance of all related systems for the next several hours, identifying the cause of the problem. A full analysis confirmed that call signaling messages were being jammed up during three timeframes, each approximately ~13 minutes, ~6 minutes, and ~5 minutes in duration. The cause of the problem was a replica \(spare\) database server unable to keep up with the synchronization from the primary systems, causing widespread delays and backups completing tasks like registration handling. Once the cause was identified as a non-production server, our team began to take immediate action by disabling its role and disconnecting it from the production systems while evaluating what was behind its performance problem. This prevented additional issues beyond those experienced. Metrics and logs indicated a likely hardware issue. Thankfully, ClearlyIP's recent investments in improving its Central US datacenter operations meant our team could quickly move the replica database to this newer environment. That migration was completed several hours after the issues began, situating the replica server in the new environment. It was then restored to service late afternoon. No similar Clearly Cloud issues were observed after the replica server was taken out of service, or since it was restored to service. Our teams will continue to proactively monitor the performance of these systems and study additional improvements which can minimize the impact of similar circumstances for the future.

   Over the course of approximately two hours, several customers in specific regions reported intermittent Call Panel connection status messages and registration timeouts with some phones.  Our support team investigated the reports and enlisted assistance from engineering while attempting to reproduce.  The problem was not definitively identified while issues were reported and may be attributable to connectivity issues or other factors outside ClearlyIP's network, but our teams will continue monitoring the situation while awaiting additional reports.

   An issue occurred on April 29th during a failover operation between elements of Clearly Cloud's core infrastructure.  This impacted Canada customers' ability to register phones and place calls for approximately 4 minutes.   Most elements of Clearly Cloud's infrastructure are designed with several redundancies and  failover occurring seamlessly without impact to customer operations.  In this case, the initial failover operation completed as expected, but the backup components did not handle the traffic they received as intended. Both the cause of the failover and the issue which caused the backup components to properly handle traffic have been identified. Improvements have been planned which should prevent similar failures.

   Our response began immediately when availability monitors detected the possibility of an issue with Clearly Cloud operations.  It was confirmed that some Clearly Cloud operations were impacted and the NOC team worked to restore full functionality as quickly as possible.  As service was restored, teams began to identify the sequence of events which caused the description and root causes.   ‌ Ultimately, it was determined that a core network switch malfunctioned for a very brief period, automatically triggering protective high-availability systems.  This led to a number of resources shifting to work around the perceived issue, leading to manual intervention due to the nature of the actual equipment failure.  ClearlyIP has initiated a proactive replacement of all switches of the same type, revised incident response protocols, and improved processes which will both reduce the likelihood of recurrence and significantly reduce recovery times for other situations.

   This was a partial outage which affected customers utilizing our Clearly Cloud USA Cloud PBX product. Customers may have intermittent registration and call issues on our Clearly Cloud USA Cloud PBX product related to an extreme CPU load change. The root cause of this was due to internal API calls that were abnormally high. As a result of this issue, the engineering team has adjusted the rate limits on the affected APIs to better deal with the situation that occurred. This helped bring our load down and back to normal levels, resolving the issues.
