network resilience

A rare alignment of failures across multiple hyperscale providers in 2025 turned routine cloud operations into a stress test for the global internet, producing multi‑hour outages that knocked popular apps, enterprise services and even public institutions offline—and left engineers, regulators...

Cloudflare confirmed that it restored services after a brief but widespread outage on December 5, 2025, that left dozens of high‑profile websites and apps — including professional networks, videoconferencing platforms, shopping and gaming services — intermittently unreachable for roughly half an...

Cloudflare’s network hiccup on December 9 exploded into another high‑profile internet outage, throttling access to widely used services and reigniting questions about the fragility that comes with concentrating so much of the web behind a single edge provider. Overview Cloudflare — the San...

The internet’s plumbing is creaking louder: in the space of a few weeks a trio of high‑profile outages knocked huge swaths of services offline, and the pattern exposes a deeper fault line in how the modern web is built, operated and regulated. Background / Overview The past two months have...

A single internal configuration change at Cloudflare briefly knocked large parts of the public web offline on November 18, 2025, exposing how concentrated and brittle modern internet edge infrastructure has become. Background Cloudflare is one of the internet’s largest edge and content-delivery...

Microsoft’s Azure platform successfully detected and neutralized a record-breaking distributed denial-of-service (DDoS) attack in late October, a multi-vector assault that peaked at 15.72 terabits per second (Tbps) and nearly 3.64 billion packets per second (pps) — the largest single cloud-based...

TPG Telecom is building a real‑time “digital twin” of parts of its 5G network to model how extreme weather, power loss and other disasters could degrade coverage and critical services — a project the company says is funded in part by a roughly $1.3 million federal grant and developed in...

Microsoft’s global outage that silenced storefronts, travel hubs and gaming portals on October 29 was traced to a control‑plane configuration error on Azure Front Door, and the affected websites were gradually returned to service after engineers halted rollouts, rolled back to a last‑known‑good...

Microsoft’s cloud fabric sputtered in a way that left email, collaboration, gaming and dozens of customer-facing websites unusable for hours — an outage Microsoft traced to an “inadvertent configuration change” in Azure Front Door that cascaded through routing, DNS and identity flows and forced...

Microsoft’s Azure platform suffered a high‑impact outage on October 29, 2025, after an inadvertent configuration change to Azure Front Door triggered DNS‑related failures that left thousands of businesses, games, productivity tools and consumer services intermittently unreachable — a stark...

Microsoft Azure customers reported widespread trouble accessing the Azure Portal and other services on October 9, 2025, after Microsoft confirmed a capacity loss in Azure Front Door (AFD) that produced intermittent portal outages and downstream service degradation across parts of Europe and...

Microsoft Azure customers across Asia, the Middle East and parts of Europe experienced measurable latency and intermittent slowdowns after multiple undersea fiber‑optic cables in the Red Sea were reported cut on September 6, 2025, forcing cloud traffic onto longer detours while Microsoft and...

Microsoft's Azure cloud felt the ripple effects of a string of undersea fiber cuts in the Red Sea on September 6, 2025, as traffic carrying vital Asia–Europe and Middle East connections was forced onto longer, more congested routes — a stark reminder that even the largest cloud platforms remain...

Microsoft’s Azure cloud briefly showed the limits of virtual resilience when several undersea fiber-optic cables in the Red Sea were cut on 6 September 2025, forcing traffic onto longer detours, producing higher-than-normal latency for cross‑region traffic, and triggering urgent...

A sudden cluster of undersea fiber cuts in the Red Sea has forced Microsoft Azure and other cloud and carrier operators to reroute traffic, producing measurable latency and slower internet performance across parts of South Asia, the Gulf and beyond—an event that exposes how a handful of damaged...

Microsoft Azure customers experienced measurable performance degradation after multiple undersea fiber‑optic cables in the Red Sea were cut, forcing traffic onto longer, often congested detours and exposing persistent structural vulnerabilities in the global internet backbone. Background /...

Microsoft warned that Azure customers could see increased latency after multiple undersea fiber-optic cables were cut in the Red Sea, forcing emergency rerouting of traffic and exposing fragile single points in global cloud and internet infrastructure. Background The disruption began on...

Internet traffic between Asia, the Middle East and parts of Europe slowed sharply after multiple undersea fibre‑optic cables in the Red Sea were severed on 6 September 2025, forcing cloud operators — most visibly Microsoft Azure — and regional carriers to reroute traffic, warn customers of...

A concentrated cluster of undersea cable failures in the Red Sea has throttled internet performance across South Asia and the Gulf, forcing cloud providers and carriers to reroute traffic and leaving businesses and consumers to contend with higher latency, intermittent packet loss, and slower...

Multiple undersea fiber-optic cables in the Red Sea were cut in early September, producing widespread internet slowdowns across South Asia, the Middle East and parts of Europe and prompting Microsoft to warn Azure customers that traffic routed through the affected corridor may experience...
