Substack Outage Map

Our outage detection system continuously monitors multiple data sources to identify disruptions in Substack services. We collect user reports, track Substack's official status pages, and run automated API checks to verify service availability. Additionally, we integrate data from third-party monitoring tools and use AI-powered anomaly detection to analyze traffic patterns and error reports, identifying outages even before they are officially acknowledged. All this data is aggregated into our real-time heatmap, visually highlighting affected regions— with darker red areas indicating more severe disruptions.
