Status pages & incidents

Keep your users in the loop.

Most monitoring tools only tell you when something breaks. DownCTL also gives your customers a real-time place to go — and keeps them informed automatically at every step.

Public status page — included on every plan

Enable a public status page for any site with a single toggle. Share the URL with your users. No separate Statuspage.io subscription needed.

Full incident lifecycle management

Publish incidents publicly when they matter, walk users through every stage with timestamped updates, then close the loop with a post mortem.

Automatic subscriber notifications

Visitors subscribe to your status page in one click. They get automatic emails when an incident opens, each time the status changes, when it resolves, and when a post mortem is published.
