    We're currently investigating a high number of infra failures. We'll update as soon as we know more details.

    We are slowly returning to normal. If you had jobs that failed with "infra-fail", those jobs can be rerun. We thank you for your patience while our engineers worked to get our system back to stability.

    A fix has been implemented and we are monitoring the results.
