Stack Overflow outages and problems
In the past 24 hours, 2 user reports came in for Stack Overflow. Counting only the 15-minute windows with a spike big enough to count as an outage, that comes to 100.00% uptime for the day.
The busiest 15-minute window had 1 report, about 20 hours ago. That stays below our outage threshold, so it doesn't count as downtime.

How to fix Stack Overflow not working
Stack Overflow is up on our end, so if it won't work for you, the problem is most likely on your side. Work through these in order:
Your browser tries to reach stackoverflow.com over your own connection, right now. Nothing is sent to us or stored.
Reload and restart
Reload the page (Ctrl+F5, or Cmd+Shift+R on a Mac), or fully close the app and open it again.
Try another connection
Switch between Wi-Fi and mobile data. If it works on one and not the other, the problem is your network, not Stack Overflow.
Update the app
Install the latest version from the App Store or Google Play. Old versions can stop connecting after a server-side change.
While Stack Overflow is down: what to use instead
- Official documentation Go to the language or framework docs when you need exact syntax and setup steps; reference pages often answer the question without a forum thread.
- MDN Web Docs Use MDN Web Docs for HTML and CSS when you want a plain reference and a working example instead of a discussion.
- GitHub Discussions Search GitHub Discussions or the project issue tracker when the problem is tied to one library or tool and other people may have hit the same error.
- Reddit programming communities Ask in a programming community on Reddit when the question is broad enough for a general forum and you need a second opinion.

How we track Stack Overflow
The status on this page comes from user-submitted problem reports for Stack Overflow, counted in 15-minute windows over the last 24 hours. Each window is compared with the normal level for Stack Overflow, so a few complaints on a quiet day don't trigger anything, but a sudden jump well above normal does.
When reports climb well above normal, the status here changes to partial outage or major outage and the chart moves with it. Stack Overflow doesn't publish a public status page that we know of, so user reports are often the quickest sign that something is wrong on their side.
