We have removed the ip address 46.252.181.103 from the domain name domain.par.clever-cloud.com.
One of our network partner has detected an abnormal amount of traffic coming to this ip address and begin to mitigate it.
We are investigating the issue
EDIT 15:15 UTC: we are still digging the issue, the abnormal traffic is over and everything seems going back to normal
EDIT 16:30 UTC : we have put back the ip address in the load balancer pool 46.252.181.103
