A Cloudflare outage right now has downed NJ Transit, X (Twitter), ChatGPT, Truth Social, Gemini, Canvas, and other major websites and apps, which has blocked user access amid major Cloudflare challenges today, Tuesday, Nov. 18. Users reported on DownDetector issues with other major apps like DoorDash, Uber, Shopify, LinkedIn, Mozilla Firefox, Amazon Web Services, Discord, and Spotify.
The NJ Transit app was not working, with train schedules and ticketing unavailable for New Jersey and NYC commuters who were hit with login issues, a “500 error” and messages reading “server connection timeout.” Truth Social — popularized and used by President Donald Trump — was down, as was popular food delivery apps, AI apps and more.
Cloudflare said on its status page it is aware of the issue “which potentially impacts multiple consumers,” noting that further information would be provided once it becomes available. Here’s the latest.
What is Cloudflare? Error explained
Cloudflare services are used by hundreds of thousands of companies globally (about 19.4%), acting as a buffer (called a Content Delivery Network, or CDN) between their websites and end users to protect them from attacks that might overload them with traffic.
Cloudflare outages are likely caused by server overloads, network bugs, cyberattacks or configuration errors. Users were met with several messages today including “Fix Cloudflare You Have Been Blocked” and these messages: challenges.cloudflare.com | 500: Internal server error, with users scrambling to “unblock” themselves.

NJ Transit app not working?
The NJ Transit website and NJ Transit app is down, which is causing travel chaos today, Nov. 18, as commuters in and out of New Jersey and New York City have been hit with Cloudflare’s outage.
Around 9 a.m., NJ Transit posted on X that due to a “vendor firewall-related issue” parts of the NJ Transit’s digital services, including njtransit.com, NJ Transit mobile app and Departure Vision were “temporarily unavailable or slow to load.” They urged patience as Cloudflare worked on a fix.
