Cloudflare Outage History

Cloudflare experienced a broad degradation starting at Sep 17, 2025 4:15 PM UTC affecting Browser Isolation, Gateway, Zero Trust Dashboard, Dashboard, and the Network. Users attempting to load sites via Browser Isolation may have encountered errors, gateway logs could fail to load in the dashboard, and HTTP 5xx errors were observed on Cloudflare's network. The incident impacted five components and persisted until Sep 18, 2025 7:20 AM UTC.

A scheduled maintenance window began in ORD (Chicago) around 7:00 AM UTC. During this window users could experience limited analytics access as Cloudflare performed maintenance.

On 5:50 AM UTC, Cloudflare reported Analytics Delays and said the issue was under investigation. A second ORD maintenance window began around 7:20 AM UTC and continued until the service was restored at 3:10 PM UTC. The incident prompted four official status updates documenting the maintenance, analytics investigation, ongoing work, and the eventual resolution. The impact was limited to analytics viewing delays and did not indicate a full service outage, with effects centered on the ORD region.

The Cloudflare platform began experiencing degraded performance at 12:55 PM UTC with API Shield reporting processing delays. Over the next several hours, connectivity errors increased for Private Relay, Zero Trust Secure Web Gateway, and WARP, resulting in slower responses and intermittent failures for users worldwide. A Singapore regional maintenance window at 6:15 PM UTC was noted, during which some components briefly returned to normal, but broader issues persisted and affected Cloudflare Workers as well.

Cloudflare published five status updates during the incident, including initial investigations, identification of the root cause and fixes, Singapore maintenance, and later reporting of Workers API latency and errors. The outage lasted approximately 9 hours and 25 minutes, from 12:55 PM UTC to 10:20 PM UTC, with service restored by 10:20 PM UTC.

Cloudflare conducted scheduled maintenance in the Newark (EWR) edge region, causing brief degradation of services for users in that area. The status page indicated the work was in progress starting around 6:00 AM UTC, with the issue listed as in progress and the service returning to normal by 10:05 AM UTC. The maintenance appeared localized to the Newark region, with no broader impact reported.

From Sep 9, 2025 5:00 PM UTC, Cloudflare reported network performance issues in Singapore that escalated into broader problems affecting multiple services. Users across APAC reported login/authentication failures, DNS and connectivity issues, and degraded performance. On Sep 12, 2025 6:06 PM UTC Cloudflare confirmed issues with the API and Cloudflare Dashboard, with knock-on effects across Zero Trust and other edge services. The incident involved more than a dozen components, including API, Dashboard, Zero Trust, CDN purge, Workers, Pages, Turnstile, Realtime Kit, Durable Objects, Gateway, Access, and SSL for SaaS provisioning. The outage lasted approximately from Sep 9, 2025 5:00 PM UTC to Sep 15, 2025 1:55 AM UTC (about 5 days).

Cloudflare experienced delays in Web Analytics processing in the European Union, causing lag in analytics data delivery for EU-based users. Other analytics features, including DNS and Rate Limiting analytics, were not affected. The outage lasted about 50 minutes, beginning at Sep 5, 2025 5:40 PM UTC and ending at Sep 5, 2025 6:30 PM UTC. Primarily the impact was in the EU region.

Cloudflare's status page documented the incident progression, with two official updates. The issue transitioned from a normal state to degraded analytics at Sep 5, 2025 5:40 PM UTC and returned to normal at Sep 5, 2025 6:30 PM UTC.

Cloudflare reported issues affecting Durable Objects in Western North America, causing degraded performance and intermittent disruption for workloads relying on Durable Objects. The incident began at 2:10 PM UTC when Cloudflare changed the status to warn and announced an investigation into a problem that could impact multiple customers.

By 4:05 PM UTC, Cloudflare had resolved the issue and returned services to normal. The provider issued 2 status updates during the incident. A small number of user reports described connectivity or data access issues, and the impact appeared regional to Western North America rather than global, with an outage duration of about 1 hour and 55 minutes.

Cloudflare conducted scheduled maintenance at the Dallas data center (DFW) on 2025-09-05. The maintenance began at 7:30 AM UTC with updates to follow as the operation progressed, and users may have seen intermittent performance during the maintenance window.

The maintenance completed with Cloudflare returning to normal at 12:05 PM UTC after roughly 4 hours and 35 minutes. The provider issued 2 status updates during the incident to keep customers informed.

Cloudflare’s R2 storage experienced elevated latency and timeouts beginning at Sep 4, 2025 9:45 PM UTC, with a scheduled maintenance window announced shortly after. The issue affected Cloudflare R2 components across services, resulting in degraded performance and intermittent timeouts for workloads relying on R2. In Kunming, China (KMG), users encountered increased HTTP 5xx errors during the incident. The outage persisted through multiple status updates and was resolved when R2 returned to normal later the next day.

Cloudflare experienced issues affecting the Cloudflare Dashboard and Cloudflare API service, with requests failing and errors displayed for users managing accounts. Cloudflare noted that CDN edge operations and cached content delivery were not impacted. The incident began at Sep 4, 2025 5:10 PM UTC and lasted for about 1 hour 30 minutes, with services returning to normal by Sep 4, 2025 6:40 PM UTC.
