What is Heroku?
Heroku is a cloud platform-as-a-service owned by Salesforce that lets developers deploy, manage, and scale web applications without managing underlying infrastructure. It supports multiple programming languages including Ruby, Node.js, Python, Java, PHP, and Go. Developers and companies rely on Heroku to host production web apps, background workers, scheduled tasks, and databases through its add-on ecosystem.
Signs Heroku is having problems
- Dynos fail to start or restart in a loop, with the app returning an H10 (App Crashed) or H14 (No Web Dynos Running) error page.
- Deployments via git push heroku main hang or time out without completing the build slug.
- Heroku Postgres add-on connections are refused or queries return errors, causing database-backed pages to fail.
- The Heroku dashboard at dashboard.heroku.com is inaccessible or shows a blank screen, preventing any management of apps or dynos.
Find out when your own services go down
You can check Heroku here — but a heartbeat monitor tells you the moment your API, website, or cron job stops responding, so you hear about your own downtime before your users do.
Frequently asked questions
How can I tell if Heroku is down?
Check the official Heroku status page at https://status.heroku.com for real-time incident reports covering the platform, router, API, and data services. You can also look at error codes returned by your app — codes in the H or R range in your logs indicate platform-level issues rather than application bugs.
Where is the official Heroku status page?
The official status page is https://status.heroku.com. It lists the current status of Heroku's runtime, API, dashboard, and data services, and includes a history of past incidents with post-mortems for significant outages.
What is the difference between a Heroku outage and my app crashing?
Heroku error codes help distinguish the two. Codes starting with H (such as H10, H12, H13) are generated by the Heroku router and usually point to platform or configuration issues. Codes starting with R (such as R14 for memory quota exceeded) point to resource limits on your specific dyno. Check your app logs with heroku logs --tail to see which type of error is occurring.
Can I get automatically alerted when my app on Heroku goes down?
The Heroku status page covers platform-wide issues, but it does not monitor your individual application. You can set up a heartbeat monitor on CronJobPro to ping your app endpoint on a schedule — if your dyno crashes or becomes unresponsive, you get an alert immediately rather than finding out from a user complaint.
