Hi All,
A bug in our last deployment has lead to a problem processing scanner reports. Since then we have mitigated the issue and the service is back to operational, while a real fix is in progress.
You can track the progress on the fix and the status of the service on our status page: https://sonarcloud.statuspage.io/
Thank You for signaling the issue (we did detect on our side, but vigilance is always good).
Janos @ SonarCloud Team
