How to fix Substack not working
Substack 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 substack.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 Substack.

How we track Substack
The status on this page comes from user-submitted problem reports for Substack, counted in 15-minute windows over the last 24 hours. Each window is compared with the normal level for Substack, 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. Substack 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.
