It uses a GraphSAGE GNN trained on BGP event streams, with Tinybird as the real-time data pipeline. Key architectural decisions include denormalizing GNN feature vectors into every event at ingest time, using Tinybird Pipes for server-side pre-aggregation before model inference, and an inverse-GDP-weighted MSE loss function that prioritizes accuracy for cities with the worst infrastructure. The model predicts an 87ms latency reduction for a Kinshasa–Lagos peering link affecting four cities currently without IXP presence. The post covers the full architecture, data model, schema evolution strategy, and engineering trade-offs for building reliable real-time ML systems on fragile networks. ## Full article daily.dev links to this article rather than hosting it.
