Not investment advice. Muhabbit scores how much a story may matter, not which way to trade.
A 2025 Red Sea subsea cable failure degraded traffic and communications quality in parts of Pakistan and the United Arab Emirates, according to the ITU's Global Connectivity Report 2025, which found subsea cables carry more than 99% of cross-border data flows. The figure covers international data only, not domestic traffic or total global internet usage, and undersea links operate alongside terrestrial networks, satellites and alternate routes that help maintain connectivity during outages. The disruption highlights how concentrated international data traffic is on a small set of subsea routes, leaving regions exposed when a single cable segment fails. Watch for cable operators and carriers to detail repair timelines and rerouting capacity, and for whether affected markets accelerate investment in redundant terrestrial and satellite paths.
