Substack not working? Try these fixes
- If the feed loads but posts won't upload, the outage may be limited to uploads or messaging.
- Update the app. Old app versions are sometimes cut off after an update on the server side.
- Log out and back in. If you're locked out, check the service's account-recovery page rather than retrying many times.
- Try another device or network, for example mobile data instead of Wi-Fi.
- Hard-refresh the page (Ctrl/Cmd + Shift + R) or open it in a private window.
- Flush your DNS cache, or switch your DNS to 1.1.1.1 or 8.8.8.8.
- Turn off your VPN, ad blocker or other browser extensions and try again.
Questions
Is Substack down right now?
We checked Substack just now and it was up. The server answered with HTTP 200 in 425 ms.
Why is Substack not working for me?
If our check shows Substack is up, the problem is most likely on your side: your network, DNS, browser extensions, or an outdated app. Try the steps above. If it shows down, the problem is on Substack's end and you'll need to wait for them to fix it.
How often do you check Substack?
Every 10 minutes, around the clock. Failed checks are retried once before they're recorded, and we keep 30 days of history.
Where do your checks come from?
From a single server in a data center. A site can be down in one region and up in another, so an outage that only affects some countries may not show up here.
