Major Outages Notifications

Substack and other vendors don't always report outages on time. Our crowdsourced status platform helps you stay ahead of outages. Users report issues and outages, sharing details on what problems they are facing. We use that info to provide early signs of outages. This way, even without an official update, you can stay ahead of possible problems.
