Heroku Status

Last updated November 06, 2019

Heroku Status provides the current status and incident history report for the Heroku platform. The status site covers all runtimes, as well as key add-ons necessary for smooth operation of production applications.

Accessing Heroku Status

The current status and history of platform issues is shown at:

https://status.heroku.com

The heroku CLI can be used to ascertain the current status:

$ heroku status
=== Heroku Status
Apps:      No known issues at this time.
Data:      No known issues at this time.
Tools:     No known issues at this time.

Status information

The status site includes the current status of the platform, the uptime for the last full month, and the most recent incidents, all broken down into three categories: apps, data, and tools.

Incident reporting will refresh every 30 seconds.

Apps and Runtime issues

Apps and Runtime issues are those that affect running, stable applications that have at least two web dynos or use a non-hobby database (or no database at all).

Components include:

  • Dynos
  • Routing
  • Scheduler

Data Service issues

Data Service issues are those that affect the health of Heroku data products.

Components include:

  • Heroku Postgres
  • Heroku Redis
  • Heroku Connect

Tools issues

Tools issues are those that affect developer workflow and management tools.

Components include:

  • Git-push deployments and the Deployment API
  • GitHub Sync
  • API / CLI / Heroku Dashboard (scaling up/down, changing configuration, etc.)
  • Logging
  • Unidling free dynos

The types of platform work that can result in notifications, and the types of notifications are documented in Platform Updates, Maintenance and Notifications.

Getting notified when there is an incident

You can sign up for email or SMS alerts when there are issues affecting the platform. Go to the status site and click on Subscribe. You can also follow the twitter feed, RSS feed, or connect to the status site via its API.

Uptime calculation

Heroku is a distributed platform spread across many different datacenters and components. During any given incident, it is rare for all applications running on the platform to be affected, and they’re usually not affected evenly.

For this reason, we report our uptime based on a combination of rate of platform errors for the month (H99s) and canary availability. Canary is our testing service which gathers platform app reliability and performance metrics by executing repeated HTTP requests against various platform endpoints as a regular external user.

Heroku Status Uptime

Once we have calculated the uptime for a given month, it will be displayed on the uptime chart. Mousing over the chart will reveal information about the date of each bar.

In addition to monthly uptime figures, we’re also showing incident occurrences on a per-day basis. These incidents are indicated in the ‘Past Incidents’ section of the status site. An incident report more than 24 hours old will be archived and accessible via the Incident Archive.

Actions to take when you suspect an outage

Check the status site if there is a current incident. If nothing is reported, or if you are experiencing something different than what is reported, contact our support team.
