This is an illustrative, lab-style postmortem — a realistic failure mode written up to teach the lesson, not a report of a real outage. In India, where fiber cuts are a weekly fact of life, this pattern is very real.

Illustrative scenario. The timeline is a reconstructed teaching scenario, not a real incident. The architecture lesson — single-path mid-mile is a single point of failure — is entirely real.
A regional CDN edge serves a metro’s ISPs. It fills from a distant origin over a single point-to-point link — one fiber path, no diverse route. Everything works perfectly… until a construction crew several districts away puts a backhoe through the cable.
Not the backhoe — backhoes are a certainty, not a surprise. The root cause was architectural: a single-path mid-mile made the link a single point of failure, and the edge had no way to keep serving live without the origin. One cut, one region down.
As we’ve written in why Indian IPTV needs a different architecture, fiber cuts here are frequent enough that single-path anything is an operational liability, not a theoretical risk. A national design has to assume the cut will happen and route around it.
HySky’s national model uses protected mid-mile paths, edges that authorise and serve locally (so a brief origin loss isn’t an instant outage), and a recommended warm-standby origin for geo-DR. The same edge-autonomy principle that survives a dead node also survives a cut link.
