[Feat/Infra]: Build an Autonomous BGP Anycast Route Optimization Engine for Global Multi-Region Proxy Nodes Ingress

Problem

When an enterprise runs distributed multi-agent clusters across multiple regions (such as USA, EU, and India), standard DNS load balancing takes minutes to propagate data updates under region-wide cloud or network path drops, dropping active processing workflows mid-flight.

Proposed Solution

Design a geo-distributed ingress routing architecture within a dedicated network platform directory internal/gateway/anycast/.

• Prototype an autonomous automation control engine that links directly with cloud provider networking APIs to run a BGP (Border Gateway Protocol) Anycast network layout.
• Broadcast a single sovereign virtual tracking IP address globally across all active localized entry connection points.
• If an entire region cluster setup encounters catastrophic network degradation, the Anycast boundary will natively reroute incoming packet traffic at the global transit tier to the nearest physical geo-cluster location without updating DNS cache limits.

Alternatives

• Geo-DNS routing rules, which are fully constrained by client-side local lookup caching and trigger structural failover lag.

Use Case

Secures high-availability disaster recovery capabilities across regional boundaries, making FaultPlane's core control engine completely un-droppable on the global map.

Additional Notes

Integrate the output telemetry channels cleanly with the non-blocking Prometheus sync modules currently defined inside deployments layouts.

Start by inspecting internal/gateway/anycast/ and the deployments layouts referenced in the issue, then identify how the project currently handles ingress and Prometheus telemetry. The issue does not name cloud providers, entry points, tests, or concrete acceptance criteria, so the BGP architecture and definition of done need to be established before implementation.
