Abstract
While the Internet continues to thrive, the resiliency of its fundamental routing infrastructure is not fully understood. In this paper, we analyze the behavior of the de facto inter-domain routing protocol, BGP, during a large-scale power outage that affected the connectivity of 3,175 networks in dozens of cities in the eastern USA and Canada. By observing proper metrics of BGP, we study BGP behavior from both the global level and the prefix level. At the global level, our results show that many global BGP metrics remained stable during the blackout event; importantly, we do not find an increase in the number of BGP announcements, a metric that has been primarily used to indicate significant changes in routing. However, we observe an apparent increase in the number of withdrawals. At the prefix level, we introduce per-prefix AS-path graphs and study their evolution for affected prefixes during the blackout; we have found that in such graphs there is a sharp decrease in the number of edges and nodes as well as changes in node degrees.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
