Cloudflare down: What we know about the outage so far
UPDATE Tuesday, Nov. 18, 9:18 a.m. ET: Cloudflare confirmed it was experiencing serious issues on Tuesday morning, noting in an emailed statement to Mashable that the root cause appeared to be "a spike in unusual traffic."
Read the statement from Cloudflare:
We saw a spike in unusual traffic to one of Cloudflare's services beginning at 11:20 UTC. That caused some traffic passing through Cloudflare's network to experience errors. We do not yet know the cause of the spike in unusual traffic. We are all hands on deck to make sure all traffic is served without errors. After that, we will turn our attention to investigating the cause of the unusual spike in traffic. We will post updates to cloudflarestatus.com and more in-depth analysis when it is ready to blog.cloudflare.com.
The latest status update from Cloudflare read that it was "working on restoring service for application services customers."
The internet appears to be breaking again.
On Tuesday morning, at 11:48 UTC, Cloudflare confirmed its global network is experiencing issues impacting "multiple customers."
Here's the full statement published on the site's status page.

Cloudflare is a service that "powers Internet requests for millions of websites and serves 78 million HTTP requests per second on average," according to its site. In short, when Cloudflare has problems, the internet has problems. Users on X are already reporting issues, and Down Detector — the site that's normally a go-to for checking what's broken and what's not — appears to be having issues itself. (Disclosure: Ziff Davis owns both Mashable and Down Detector.)
It's worth noting this isn't the first time Cloudflare has experienced major issues. Large portions of the internet went down back in June due to Cloudflare disruption, causing problems for users of Twitch, Etsy, Discord, and Google.
