Post-Mortem Report

Incident: Service Outage – Infrastructure Disruption at Data Center

Incident ID: ED-2026-06-07-DC01
Start Time: June 7, 2026 – 10:34 AM UTC
End Time: June 10, 2026 – 5:35 PM UTC
Duration: Approximately 79 hours
Severity: Critical

Executive Summary

Between June 7 and June 10, 2026, EnderDevelopment experienced a major infrastructure incident that resulted in widespread service disruption affecting multiple public-facing and internal services.

The incident originated from a large-scale network attack targeting infrastructure within our hosting provider DeluxHost's data center environment. During the course of the event, a separate storage-related failure occurred within the provider-managed infrastructure, resulting in filesystem corruption on critical infrastructure components.

The combination of sustained network instability, storage corruption, recovery operations, and subsequent attack escalation significantly extended restoration efforts.

While the initial infrastructure failure, storage corruption, and unstable uptime conditions were caused by issues within DeluxHost's infrastructure environment, we acknowledge that the duration of the recovery process, restoration procedures, validation phases, and service reactivation timelines were our responsibility. We recognize that these processes took longer than expected and are committed to improving our recovery capabilities.

All services have now been fully restored and validated. No customer data loss has been identified.

Impact

Affected services included:

• enderdevelopment.com

• dash.enderdevelopment.com

• AI Platform

• Internal infrastructure services

• AMS-1 Main Server

• Network services connected to affected infrastructure

Users experienced:

• Complete service unavailability

• Intermittent connectivity issues

• Dashboard access interruptions

• API availability degradation

• Temporary inability to access hosted resources

No evidence of customer data loss, unauthorized access, or database integrity compromise was identified.

What Happened

Phase 1 – Initial Infrastructure Disruption

On June 7, our monitoring systems detected a significant infrastructure disruption originating within DeluxHost's upstream data center environment.

Shortly afterward, a large-scale network attack exceeding 10 Tbit/s was identified affecting portions of the provider's infrastructure.

The attack generated severe instability across upstream networking systems and significantly impacted service availability.

Phase 2 – Storage Failure and Filesystem Corruption

While mitigation efforts were ongoing, a storage-related technical failure occurred on affected infrastructure managed by DeluxHost.

This failure resulted in filesystem corruption and prevented safe startup of several services.

At this stage, restoring service availability became secondary to protecting data integrity.

Services were intentionally kept offline to avoid additional writes to corrupted filesystems and to prevent further damage.

Phase 3 – Recovery Operations

Recovery operations included:

• Filesystem integrity verification

• Storage validation procedures

• Backup verification

• Data consistency checks

• Infrastructure reconstruction where required

• Progressive restoration of network services

• Database validation and synchronization

The recovery process required extensive manual validation before systems could be safely returned to production.

Although the underlying infrastructure incident originated outside of EnderDevelopment's control, the recovery, restoration, validation, and service reactivation phases were managed by our team. We acknowledge that these procedures can be improved to reduce recovery times during future incidents.

Phase 4 – Service Restoration

Beginning June 8, services were gradually restored in controlled phases.

The official website was restored first, followed by dashboard infrastructure and associated services.

Each component was validated independently before being returned to production.

By June 8, all major services had been restored and entered active monitoring.

Phase 5 – Secondary Network Instability

Following restoration, attack activity intensified once again.

Although services and data had been successfully recovered, intermittent connectivity issues continued due to instability within DeluxHost's upstream network environment.

This resulted in users experiencing occasional online/offline behavior despite services operating correctly internally.

The provider deployed additional mitigation systems and later performed a migration to a different rack within the data center to isolate the affected infrastructure and improve network stability.

Phase 6 – Final Resolution

After the infrastructure migration and extended monitoring period, network stability returned to normal levels.

Final validation confirmed:

• Service availability restored

• Stable network connectivity

• Healthy storage systems

• Successful database synchronization

• No customer data integrity issues

The incident was formally closed on June 10, 2026.

Root Cause

The incident resulted from multiple independent events occurring simultaneously:

1. A large-scale network attack exceeding 10 Tbit/s targeting infrastructure within DeluxHost's environment.

2. Network instability generated by the attack and associated mitigation activities.

3. A storage-related infrastructure failure within the provider environment that caused filesystem corruption.

4. Extended recovery requirements due to the need to preserve and validate data integrity before restoration.

The initial infrastructure disruption, storage corruption, and unstable uptime conditions were caused by failures and instability within the provider-managed environment.

No evidence indicates that EnderDevelopment applications, software deployments, or customer actions caused the incident.

Responsibility and Accountability

Transparency is important to us, and we believe it is necessary to clearly distinguish responsibilities associated with this incident.

DeluxHost Responsibility

• The large-scale network disruption originated within DeluxHost's infrastructure environment.

• The storage-related failure that resulted in filesystem corruption was the result of a combination of factors involving both provider-managed infrastructure and our own infrastructure components, contributing jointly to the incident.

• The intermittent uptime and network instability experienced throughout portions of the incident were caused by upstream provider issues and ongoing mitigation efforts.

EnderDevelopment Responsibility

• Recovery planning and execution.

• Backup validation and restoration procedures.

• Infrastructure reconstruction and service restoration.

• Internal incident coordination.

• Communication with users during the recovery process.

• Overall recovery timelines once infrastructure access became available.

While the root infrastructure failures were outside our direct control, we acknowledge that our recovery process took longer than desired. We accept responsibility for improving the speed, efficiency, and coordination of future recovery operations.

Resolution Actions

During the incident we:

• Coordinated directly with DeluxHost and the data center provider.

• Performed emergency infrastructure assessment.

• Validated filesystem integrity.

• Executed recovery procedures on affected systems.

• Restored services in phased deployments.

• Conducted database consistency verification.

• Maintained continuous monitoring throughout recovery.

• Worked with the provider during network mitigation efforts.

• Validated all restored services before returning them to production.

Preventive Measures

To reduce the likelihood and impact of similar incidents in the future, both EnderDevelopment and our infrastructure provider, DeluxHost, are implementing a series of improvements.

DeluxHost has assured us that they are committed to strengthening their network protection systems, improving large-scale attack mitigation procedures, and increasing overall infrastructure resilience against future attacks and related disruptions.

On our side, we will focus on improving backup management, reducing single points of failure within our infrastructure, enhancing recovery procedures, and strengthening monitoring and validation processes to ensure faster and safer recovery in the event of future incidents.

Lessons Learned

This incident highlighted the importance of prioritizing data integrity over rapid service restoration.

Although recovery required significant downtime, maintaining systems offline during critical phases prevented additional corruption and allowed a complete recovery without identified customer data loss.

The event also demonstrated the effectiveness of our backup, validation, and recovery procedures under extreme conditions, while simultaneously revealing areas where recovery speed and coordination can be improved.

Going forward, we will invest in additional backup recovery points, stronger disaster recovery automation, and closer operational coordination with DeluxHost to reduce recovery times and improve incident response efficiency.

Final Status

All services are operational.

While the vast majority of customer data was successfully recovered and validated, a very small fraction of data could not be restored due to the storage corruption event. As a result, a limited number of users may find that certain projects or recently modified resources are no longer available. Based on our analysis, the affected data represents only a minimal portion of the overall platform data, and the impact is limited to a very small number of users. No widespread data loss or integrity issues have been identified.

No ongoing infrastructure issues remain related to this incident.

We sincerely thank all users, customers, and partners for their patience, understanding, and support throughout this event.

Signed by EnderDevelopment Team

We are pleased to confirm that this incident has now been fully resolved.

Following the overnight infrastructure migration and extensive monitoring, all affected services are operating normally and network stability has been fully restored. No further interruptions, connectivity issues, or abnormal behavior have been observed.

Throughout the recovery process, our teams worked closely with the data center provider to mitigate the effects of the large-scale network attack, recover from the subsequent storage-related failure, and safely restore all infrastructure components. Final validation checks have been completed successfully, and all systems are now functioning as expected.

We can also confirm that no customer data loss or integrity issues have been identified as a result of this incident.

The incident is now officially closed. We will continue routine monitoring as part of our standard operations, and a detailed post-mortem report will be published in the coming days outlining the root causes, timeline of events, response actions, and preventive measures being implemented.

We would like to sincerely thank all users for their patience, understanding, and support throughout this incident. Your cooperation during this challenging recovery period has been greatly appreciated.

We are pleased to report that the situation is now progressively stabilizing.

Over the past hours, our infrastructure provider has implemented additional mitigation measures and we have observed a significant improvement in overall service stability. While some intermittent connectivity issues may still occur, the frequency and impact of these disruptions have been steadily decreasing.

To further improve reliability and prevent any recurrence of the network instability experienced during this incident, our provider has scheduled a migration of the affected infrastructure to a more stable rack within the data center during the night. This operation is expected to provide a definitive resolution to the remaining network-related issues.

At this time, all core services remain operational and no data integrity issues have been identified. The remaining instability is limited to the provider's network environment and does not affect customer data, virtual machines, or application-level services.

If the migration proceeds as expected and stability continues to improve, we anticipate being able to formally close this incident following final validation and monitoring.

We thank all users for their patience, understanding, and support throughout this exceptionally challenging event. Further updates will be provided if necessary; otherwise, a detailed post-mortem report will follow after the incident is officially closed.

We want to provide an important clarification regarding the current instability of our services.

Since the last update, we have observed that the attack activity has further intensified, resulting in intermittent connectivity issues across parts of the infrastructure. While core systems remain restored, users may still experience irregular availability, with services appearing online and offline unpredictably.

At this stage, we can confirm that this behavior is not related to any issue with application data, virtual machines, or internal deployments. The instability is strictly tied to the network layer and upstream infrastructure managed by our data center provider.

Our hosting provider is currently on-site at the data center and actively working to stabilize the network environment and mitigate ongoing disruption. We are in continuous coordination with their engineering team to ensure full resolution as quickly as possible.

We appreciate your patience as we continue working through this extended recovery phase. Further updates will follow as soon as network stability is fully restored.

Service Restoration Complete

All major services have now been successfully restored.

Both enderdevelopment.com and dash.enderdevelopment.com are fully operational and accessible to users. Our team will continue to closely monitor the infrastructure over the coming hours to ensure stability and rapidly address any unexpected issues.

Please note that while the platform is operational, the database restoration and synchronization process is still ongoing in the background. Some data may continue to be validated and synchronized as part of the final recovery phase, although no major service interruptions are expected.

We would like to thank all users for their patience and understanding throughout this incident.

A detailed post-mortem report will be published in the coming days, providing a complete timeline of events, the impact assessment, and the corrective actions taken.

As an early summary, the incident originated from a combination of multiple factors, including:

• A large-scale network attack exceeding 10 Tbit/s.

• A subsequent storage-related technical failure that resulted in disk corruption.

• A complex recovery process requiring extensive infrastructure validation and restoration procedures.

Despite the severity of the incident, our backup and recovery systems allowed us to successfully restore services and return the platform to operational status.

We will continue monitoring all systems while preparing a full technical report for transparency and future prevention efforts.

The official website enderdevelopment.com has been successfully restored and is now fully accessible to users.

We are currently continuing recovery operations on dash.enderdevelopment.com, which remains temporarily unavailable while final stability checks and data integrity validations are being completed.

Estimated time of restoration for the dashboard is up to 20 minutes.

We appreciate your patience as we complete the final phase of the recovery process and ensure full system stability.

We are currently in the process of restoring services following a major infrastructure disruption.

At this stage, some components of our systems are already partially operational and may be reachable, while other services are still undergoing recovery and validation procedures.

The restoration is being carried out in phases to ensure system stability and prevent any further data integrity issues.

We are actively monitoring all services and gradually bringing infrastructure back online as each component is verified and confirmed stable.

We appreciate your patience and understanding as we continue working toward full restoration

We are currently operating under a high-pressure incident response due to a significant data corruption event affecting parts of our infrastructure.

At this time, we want to clarify that this issue does not directly impact EnderDevelopment Dash or user-level application data, which remains isolated and intact. However, the disruption affects a broader portion of our internal infrastructure and hosting systems.

For safety reasons, we are keeping services offline intentionally to prevent any further data corruption while recovery and validation procedures are still in progress.

Our engineering team is actively working in coordination with the infrastructure provider to stabilize the environment, validate filesystem integrity, and progressively restore services in a controlled manner.

We sincerely apologize for the disruption and understand the inconvenience this may cause. Our priority is ensuring data integrity before service restoration, even if this extends downtime.

Further updates will follow as soon as we reach a stable recovery milestone.
