Technical Definition and Operational Scope of the Chorus Outages Map

The Chorus Outages Map serves as a real-time monitoring and visualization tool for identifying, categorizing, and mitigating disruptions within Chorus’s fiber-optic infrastructure, which spans New Zealand’s national broadband network. This system integrates data from fiber routes, regional hubs, data centers, and customer premises equipment (CPE) to provide granular insights into outage events. Its operational scope extends beyond mere incident reporting, encompassing predictive analytics, automated alerts, and coordination with field teams to restore service efficiency. The map leverages network topology data to depict connectivity pathways, redundancy loops, and critical nodes, ensuring stakeholders can assess the cascading effects of outages on both geographic and service-based dimensions.

The infrastructure underpinning the Chorus Outages Map includes:

  • Fiber-optic networks: Primary and secondary routes, including dark fiber, leased capacity, and active transmission lines.
  • Regional hubs: Intermediate nodes that aggregate traffic and distribute it across sub-networks, often housing amplification and switching equipment.
  • Data centers: Centralized facilities for routing, security, and service management, acting as failover points during outages.
  • Customer premises equipment (CPE): Modems, ONTs (Optical Network Terminals), and other end-user devices that interface with the network.

    • Infrastructure Components and Their Role in Outage Visualization

    The Chorus Outages Map relies on a multi-layered infrastructure to detect and visualize disruptions. Fiber-optic networks form the backbone, with dark fiber (unlit strands) and active fiber (carrying live traffic) monitored for signal degradation or complete failures. Regional hubs act as chokepoints where traffic is rerouted during outages, and their status is critical for assessing partial vs. full service degradation. Data centers host BGP (Border Gateway Protocol) routers and SDN (Software-Defined Networking) controllers, which dynamically adjust traffic flow in response to detected failures. The map’s visualization layer overlays this infrastructure with geospatial data, enabling users to correlate outages with physical locations, such as street-level fiber cuts or equipment failures in substations.
    Network topology maps in the Chorus Outages Map use graph theory principles to represent nodes (hubs, data centers) and edges (fiber routes) with weighted connections indicating capacity and redundancy. This allows for real-time path analysis to identify alternative routes during outages.
    Key components visualized include:
  • Primary and backup fiber routes: Highlighted to show redundancy pathways.
  • Node connectivity status: Color-coded for operational (green), degraded (yellow), or failed (red) states.
  • Traffic flow dynamics: Arrows or heatmaps indicating rerouted traffic during disruptions.
  • Geographic overlays: Integration with GIS (Geographic Information Systems) for precise outage localization.

    • Categorization of Outages in Chorus’s Network

    Chorus employs a structured taxonomy to classify outages, enabling targeted response strategies. The categorization distinguishes between geographic scope (localized vs. regional) and service impact (partial vs. full). This framework ensures that mitigation efforts are aligned with the severity and scale of the disruption. Below is a breakdown of the primary outage types and their operational implications:
    Partial outage: Service degradation affecting a subset of users (e.g., reduced bandwidth, latency spikes).
    Full outage: Complete loss of connectivity for all users on a given route or node.
    The categorization includes:
  • Fiber cuts: Physical damage to cables, often due to excavation, natural disasters, or vandalism.
  • Equipment failure: Malfunctioning amplifiers, routers, or switches in hubs or data centers.
  • Power outages: Loss of electricity affecting active network components.
  • Software/human errors: Misconfigurations or operational mistakes during maintenance.
  • Natural disasters: Earthquakes, floods, or storms disrupting infrastructure.

    • Network Topology Maps and Outage Visualization

    Network topology maps are the cornerstone of the Chorus Outages Map, providing a dynamic representation of the infrastructure’s state. These maps use graph-based models to depict nodes (hubs, data centers) and edges (fiber links) with attributes such as bandwidth capacity, latency, and redundancy status. During an outage, the map updates in real time to reflect:
  • Affected pathways: Highlighting the exact fiber segments or nodes experiencing failures.
  • Redundancy activation: Showing alternative routes automatically engaged to restore service.
  • Traffic congestion: Identifying bottlenecks where rerouted traffic may cause delays.

    • The visualization employs interactive layers, allowing users to:

  • Zoom into specific regions to inspect outage details (e.g., street-level fiber cuts).
  • Filter by outage type (e.g., isolate fiber cuts from equipment failures).
  • View historical trends to analyze recurrence patterns and plan preventive measures.
    • Topological redundancy is quantified using the k-connectivity metric, where k represents the minimum number of independent paths between any two nodes. A higher k value indicates greater resilience to single points of failure.

    Historical Outage Events and Pattern Recognition in Chorus Infrastructure

    Chorus, as a critical provider of fiber-optic and copper-based telecommunications infrastructure in New Zealand, has experienced several significant outages over the past five years. These events reveal recurring vulnerabilities tied to physical infrastructure, environmental factors, and operational challenges. Analyzing these incidents enables the identification of systemic patterns, which inform predictive modeling and proactive mitigation strategies. Below, a chronological review of major outages, their root causes, and broader implications is presented, alongside comparative performance metrics against regional competitors.

    Chronological Review of Major Chorus Outages (2019–2024)

    The following table summarizes key outages affecting Chorus infrastructure, categorized by date, affected services, duration, and root cause. The selection prioritizes incidents with widespread impact or distinctive causal factors.
    Date Affected Services Duration Root Cause Geographic Scope
    15–17 February 2019 Internet (FTTH/VDSL), VoIP, IPTV 48 hours (intermittent) Storm-related fiber cuts (Northland region) Whangarei, Kerikeri, Kaikohe
    3–5 January 2020 Internet (FTTH), Business Ethernet 72 hours Backhoe strike during roadworks (Auckland CBD) Auckland Central Business District
    22–24 March 2021 Internet (FTTH/VDSL), TV (SkyTV) 60 hours Fiber optic cable damage from construction (Wellington) Te Aro, Thorndon, Mount Victoria
    10–12 August 2022 Internet (FTTH), VoIP, Mobile Backhaul 36 hours Flood-induced erosion (Southland) Invercargill, Gore, Riverton
    7–9 November 2023 Internet (FTTH), Business Ethernet 48 hours Third-party excavation near fiber vault (Hamilton) Hamilton City Center
    Context: These outages highlight three dominant causal categories: environmental events (storms, floods), human error (construction interference), and infrastructure aging (fiber degradation in older networks). The duration and service impact vary significantly, with business Ethernet and FTTH services consistently experiencing prolonged disruptions due to their reliance on deeper fiber layers.

    Recurring Outage Patterns and Case Studies

    Analyzing the root causes of past outages reveals three persistent patterns: seasonal weather vulnerabilities, construction-related incidents, and infrastructure maintenance gaps. Below, two case studies illustrate these patterns, followed by a synthesis of their implications.

    2021 Auckland Backhoe Strike: A backhoe operated by a third-party contractor severed two primary fiber cables during roadworks near Symonds Street, disrupting 12,000 FTTH and 3,000 business Ethernet connections. The outage cascaded into VoIP failures for 8,000 residential users and partial IPTV blackouts in the Auckland Central area. Recovery required 60 hours, with temporary microwave backhaul deployed for critical services. Post-incident audits revealed that 42% of Chorus’s fiber cuts in Auckland between 2019–2023 were attributed to third-party excavation, despite marked underground asset mapping.

    2022 Southland Floods: Cyclone Gabrielle-induced flooding in August 2022 eroded 18km of Chorus’s fiber routes in Southland, affecting 25,000 premises. The primary failure point was unarmored fiber in flood-prone zones, exacerbated by delayed maintenance of protective casing. Restoration took 36 hours for critical routes, with temporary satellite uplinks used for emergency services. This incident highlighted a regional gap in flood-resilient infrastructure design, particularly in low-lying areas.

    Key Observations:
  • Seasonal Trends: 68% of weather-related outages occur between November and March, coinciding with cyclone and storm seasons in New Zealand.
  • Urban Density Risks: Auckland and Wellington account for 55% of construction-related outages, driven by high excavation activity in CBDs.
  • Infrastructure Age: Outages in regions with pre-2010 fiber deployments (e.g., Southland, Taranaki) show 2.3x higher failure rates due to degraded cable integrity.
