Subsea Cable Resilience Rerouting Register

PROBLEM: On 6 September 2025, multiple subsea cables (SMW4, IMEWE, and FALCON per later reporting) were cut near Jeddah, slowing internet across India, Pakistan, the UAE and the Gulf and raising Microsoft Azure latency in the Middle East from 05:45 UTC; Microsoft rerouted traffic through alternate paths (traffic not interrupted, latency higher), and repairs were expected to take weeks. The incident exposed the Red Sea as a single chokepoint and the global repair fleet (~62 vessels) as a bottleneck. There is no register of chokepoint-risk, rerouting decisions, and repair-fleet capacity for the cables cloud and AI workloads depend on.

SOLUTION: A subsea cable resilience rerouting register: every chokepoint cut logged with cables affected, traffic impact, rerouting path, and repair time — so the next cut meets a plan, not a scramble.

EVIDENCE BASIS: DOCUMENTED for the event and impact — AP / Broadband Breakfast reporting, Sept 2025, corroborated by Microsoft Azure status and NetBlocks (cuts, timing, Azure latency). Meta Petal (1 Pb/s design, service 2029) and Ciena's 800 Gb/s over 16,608 km are REPORTED (vendor announcements; design targets/trial figures, not operating records).
