Cloudflare handles more than 20% of all internet traffic. It acts as a reverse proxy, CDN, DDoS protection layer, and DNS resolver for millions of websites. When Cloudflare has problems, the effect is unlike almost any other single service outage — thousands of different sites across unrelated industries fail at the same time.
What Cloudflare actually does
When you visit a website that uses Cloudflare, your request does not go directly to that site's server. It first goes to Cloudflare's global network, which caches content, filters malicious traffic, and routes your request to the nearest fast path to the origin server.
This means Cloudflare failures manifest in a distinctive way: the website itself may be completely operational, but because Cloudflare sits between the site and its visitors, those visitors see Cloudflare error pages (the famous "Error 1016" or "Error 523") instead of the actual site.
The 2022 Cloudflare outage
In June 2022, a Cloudflare misconfiguration during a network change caused a major outage affecting 19 of its data centres. The result was that thousands of websites — including Shopify, Discord, Crunchyroll, and many others — became unavailable or severely degraded for approximately one hour.
The incident was caused by a change to Cloudflare's internal backbone network that inadvertently withdrew routes, making those data centres unreachable. The fix required careful rollback of the network changes.
Cloudflare published a detailed post-mortem explaining the root cause, which is a model of transparency that the industry appreciates.
How to tell if Cloudflare is the issue
The signature of a Cloudflare-caused outage is multiple unrelated websites all failing simultaneously. If you cannot reach your streaming service, your work tools, and your favourite news site at the same time, Cloudflare is a likely common factor.
Specific error codes are also a giveaway. Cloudflare errors typically show codes in the 5xx range with Cloudflare branding — "Error 502 Bad Gateway," "Error 524 A Timeout Occurred," or the Cloudflare logo on the error page.

Recovery during a Cloudflare outage
During a Cloudflare outage, most affected sites have no independent fix — the problem is upstream of their servers. Some sites implement fallback routing to bypass Cloudflare for their traffic, but this is uncommon.
As a user, you generally cannot work around a Cloudflare outage except by waiting. Some websites publish their origin IP address in DNS, allowing direct access if you know the IP, but this bypasses Cloudflare's security features and is not something most sites support.
Cloudflare outages are typically resolved within 30 to 90 minutes, and Cloudflare maintains an excellent track record of transparency and fast response.
