A highly desirable property of networks is robustness to failures. Consider a metric space ( X,d X ) , a graph H over X is a ϑ -reliable t -spanner if, for every set of failed vertices B ⊂ X , there is a superset B + ⊇ B such that the induced subgraph H [ X ∖ B ] preserves all the distances between points in X ∖ B + up to a stretch factor t , while the expected size of B + is as most ( 1 + ϑ )∣ B ∣ . Such a spanner could withstand a catastrophe: failure of even 90% of the network. Buchin, Har-Peled, and Ol´ah [2019,2020], constructed very sparse reliable spanners with stretch 1 + (cid:15) for Euclidean space using locality-sensitive orderings. Har-Peled and Ol´ah [2020] constructed reliable spanners for various non-Euclidean metric spaces using sparse covers. However, this second approach has an inherent dependency on the aspect ratio (a.k.a. spread) and gives sub-optimal stretch and sparsity parameters. Our contribution is twofold:
