Cloudflare Radar Outage Center

The Cloudflare Radar Outage Center is the public catalogue of Internet disruptions maintained by the Cloudflare Radar team at radar.cloudflare.com/outage-center. It sits on top of Cloudflare Radar's per-country / per-AS / per-region telemetry and surfaces detected and confirmed outage events — "observed traffic anomalies" that are either tagged with a known cause (political shutdown, grid collapse, natural disaster, cable incident, vendor software failure) or left in the untagged-anomaly feed until attribution arrives.

What it exposes

  • Confirmed outage catalogue — events tagged with cause, affected country / region / AS, start/end timestamps, and links to any public communications from operators or regulators.
  • Traffic anomalies feed — machine-detected deviations from per-country / per-AS baselines that may or may not be outages, visible at radar.cloudflare.com/outage-center#traffic-anomalies. The 2026-04-28 quarterly review explicitly disclaims exhaustive coverage: "This post is intended as a summary overview of observed and confirmed disruptions and is not an exhaustive or complete list of issues that have occurred during the quarter. A larger list of detected traffic anomalies is available in the Cloudflare Radar Outage Center."
  • Quarterly narrative reviews — every quarter the Radar team publishes a long-form blog post summarising the confirmed outages and their mechanisms. Canonical instance of the quarterly Internet disruption review shape. See sources/2026-04-28-cloudflare-q1-2026-internet-disruption-summary for the Q1 2026 review.

Relationship to Cloudflare Radar

Where Cloudflare Radar provides the underlying telemetry surface (per-AS traffic, BGP view, DNS query shapes, IPv6 posture, protocol adoption), the Outage Center is the human-curated layer on top that turns raw anomaly signals into an attributable, linkable, externally-cite-able catalogue. Each quarterly review post cites Radar country / AS / region URLs directly — radar.cloudflare.com/ir, radar.cloudflare.com/as43754 — so readers can drill from the narrative summary back to the live data.

Seen in

  • sources/2026-04-28-cloudflare-q1-2026-internet-disruption-summary — canonical instance of the Outage Center as the curation layer over Radar's anomaly feed. Q1 2026 confirmed outage set: government-directed shutdowns in Uganda, Iran, and the Republic of Congo; national grid collapses in Cuba (×3), Paraguay, the Dominican Republic, Moldova; military-infrastructure strikes on Ukrainian power infrastructure (January 7-8, January 26) and on AWS me-central-1 + AWS me-south-1 (March 1-2, March 23); Storm Kristin in Portugal; the WACS submarine cable incident in the Republic of Congo; Verizon Wireless (software); Flow Grenada (likely routing); Orange Guinée (undisclosed); TalkTalk UK (undisclosed). Individual events linked via their own Radar URLs or via Cloudflare Radar social posts on X / Bluesky / Mastodon.
  • sources/2026-05-27-cloudflare-irans-internet-is-partially-restored-cloudflare-radar-data-shows — duration update + first-recovery snapshot for the Iran February 28 shutdown catalogued in the Q1 review. 87 days to first partial restoration on May 26 2026, qualifying as "one of the longest sustained Internet disruptions observed in recent years." Recovery shape was capital-localised (91.6% Tehran), establishing the concepts/capital-localized-internet-restoration shape on the Outage Center timeline. Recovery flagged as potentially temporary — the Outage Center's role here is to track whether the May 26 recovery holds vs reverses (as January precedent had two reversed restorations before durable recovery).
