When an attack is detected on your services, you will receive a notification via email. You can track the progress of the situation via the OVHcloud Control Panel, which will provide you with statistics. Also, when the attack is over, we will notify you via another email. If you think that your services have been targeted by a DDoS attack and your users are experiencing degraded performance, please feel free to contact the OVHcloud support team, who can look into this.
