About This Site

This shows the service availability of the API Platform.

You can subscribe to updates on any issues we have.

Using the charts, you can track the performance of our production environment over time. We use an external monitoring service to reflect real world internet delays in our response time measurements. However your mileage may vary.

We do not show the availability of individual APIs. If you have a question about a specific API, please contact us at https://developer.service.hmrc.gov.uk/developer/support.
