Microsoft issued an urgent alert on Saturday after multiple undersea fibre-optic cables in the Red Sea were discovered cut, triggering increased latency for Azure customers and underscoring how fragile the physical backbone of the global internet remains.
Overview
The disruption — first detected...
Multiple undersea fibre-optic cables in the Red Sea were cut in early September, producing widespread internet slowdowns and raising fresh questions about the fragility of the global network that underpins cloud services, financial markets and everyday communication across Asia, the Middle East...
Microsoft confirmed that parts of its Azure cloud experienced higher‑than‑normal latency after multiple undersea fiber‑optic cables in the Red Sea were cut, forcing traffic onto longer detours and exposing a brittle chokepoint in the global internet backbone. (reuters.com)

Microsoft confirmed on September 6 that multiple undersea fibre‑optic cables in the Red Sea were cut, and warned Azure customers that traffic which “previously traversed through the Middle East” may experience increased latency as packets are rerouted across longer, often congested alternatives...
Microsoft Azure warned customers of higher‑than‑normal latency after multiple undersea fiber‑optic cables in the Red Sea were cut, forcing traffic onto longer detours while carriers and cloud operators rerouted traffic and prepared for complex maritime repairs. (reuters.com)
Background /...
Undersea fibre links in the Red Sea were cut in early September 2025, producing measurable internet slowdowns and elevated cloud latency across South Asia, the Gulf and parts of Africa as operators scrambled to reroute traffic while investigators and repair crews worked to identify the physical...
Microsoft confirmed that parts of Azure are seeing higher‑than‑normal network latency after multiple undersea fiber‑optic cables in the Red Sea were cut, forcing traffic onto longer detours while carriers and cloud engineers reroute, rebalance capacity, and schedule repairs. (reuters.com)...
Microsoft’s Azure cloud experienced measurable performance degradation after multiple undersea fiber‑optic cables in the Red Sea were cut, forcing traffic to detour around the damaged corridor and producing higher‑than‑normal latency for flows that traverse the Middle East between Asia and...
Multiple undersea fiber‑optic cables in the Red Sea were cut on September 6, 2025, triggering widespread latency and connectivity problems for traffic between Asia, the Middle East and Europe and forcing cloud operators — most visibly Microsoft Azure — to reroute traffic while repair and...
Microsoft Azure customers worldwide experienced elevated latency and intermittent slowdowns after multiple undersea fiber‑optic cables in the Red Sea were damaged, forcing traffic onto longer detours while Microsoft rerouted and rebalanced network flows and coordinated with carriers and cable...
Microsoft says most Azure services continued operating, but customers experienced higher‑than‑normal latency after multiple international submarine fiber‑optic cables in the Red Sea were severed, forcing traffic onto longer alternative routes while carriers and cloud engineers rerouted...
Microsoft’s cloud customers were jolted on September 6 when Microsoft confirmed that multiple international subsea fiber-optic cables in the Red Sea had been cut, producing measurable latency and service degradation for Azure traffic that transits the Middle East corridor and forcing engineers...
Microsoft warned that parts of the Azure cloud were experiencing higher‑than‑normal latency after multiple undersea fiber‑optic cables in the Red Sea were cut, forcing traffic onto longer, more congested routes while carriers and Microsoft reroute and plan repairs. (reuters.com)
