About this tag
Capacity rebalancing refers to the process of rerouting network traffic and redistributing load after infrastructure disruptions, such as undersea cable cuts. In September 2025, multiple fiber-optic cables in the Red Sea were cut, causing latency spikes and performance degradation for Microsoft Azure customers across Asia, the Middle East, and Europe. Microsoft and regional carriers responded by rerouting traffic onto longer alternate paths and rebalancing capacity to minimize user impact. This tag covers discussions about how cloud providers and carriers manage capacity during cable outages, the technical challenges of rerouting global internet traffic, and the structural vulnerabilities exposed by such events. Topics include Azure latency, submarine cable disruptions, and network resilience strategies.
