Service Level Agreement
Version 2 is architected in such a way to be able to survive an outage of a single data-centre (AWS Availability Zone) in order to achieve a high level of service availability.
The administration interface is built as a web application, and as such requires a modern web browser. For the administration interface, web browser versions with greater than 0.2% of global usage are supported on a best effort basis, with the exception of Opera Mini and browsers deprecated by their vendor. No support guarantee is made for a web browser which does not meet this requirement.
For the reporting interface, a “progressive enhancement” technique is used to maximise browser support. Our intention is to provide a basic level of usability to all browsers, with a full-level of support to all web browsers with greater than 0.2% of global usage, with the exception of Opera Mini and browsers deprecated by their vendor.
The administration interface and public site are tested with the following browsers to verify this:
- Google Chrome on Windows, macOS and Android (latest version only)
- Firefox on Windows and macOS (latest version only)
- Safari on iOS and macOS (latest version only)
- Internet Explorer (latest version only)
- Edge (latest version only)
