To ensure maximum resilience, we are conducting a series of controlled fiber failover simulations across our network to validate our modernized backbone architecture.
Following extensive lab testing, this maintenance serves as the final real-world validation of all routing protocols and convergence behaviors during physical link failures.
Scope & Expected Behavior • Affected Services: All dataforest locations and products. • Network Behavior: This is not a total network outage. Cuts are executed sequentially across our various dark fiber links, affecting only individual paths at a time. • Traffic Rerouting: Per cut event, affected external paths are expected to experience a short packet loss / rerouting window of approximately 20 to 60 seconds. • Internal Traffic: Network connectivity within the same datacenter is completely unaffected. Traffic flowing between different dataforest locations (e.g., cross-site backups) will experience the same temporary rerouting behavior as external traffic.
Execution & Safety Measures • Phased Rollout: Testing will follow a strict, phased execution strategy to minimize customer impact: initial dry runs on non-productive traffic → graceful software-initiated cuts (which are expected to cause no packet loss at all but come with a residual risk) → physical fiber disconnects. • Multiple Events: Each of our dark fibers will be tested sequentially in multiple iterations (both graceful and physical). • Operational Focus: During the active test procedure, engineering focus remains 100% on execution, monitoring, and immediate remediation if unexpected behavior occurs. Live status updates will be paused during active cut windows; a comprehensive closing update will be published upon completion of the test suite. • Objective: Proactively validating these failover scenarios under controlled conditions ensures that our network redundancy operates within expected timeframes during actual emergencies.
Customer Action Suggested • BGP & IP Transit Customers: Please actively reroute your upstream traffic away from dataforest for the duration of the maintenance window to avoid rerouting delays. • Multi-Location & High-Availability Workloads: If your infrastructure permits draining a location or temporarily removing dataforest nodes from global load balancing pools, we strongly recommend doing so prior to the test window.
