We are facing TCP-SYN flood attack on port 25 of hosting server “cp-40.webhostbox.net” (184.108.40.206), due to which the below mentioned subnet is under mitigation.
Subnet : 220.127.116.11/24
Affected IP address : 18.104.22.168
Affected Services : Mail service hosted on the server “cp-40.webhostbox.net”.
We have applied global filters on the IP address “22.214.171.124” in which we have noticed the attack. You should not face any issues on other IP addresses of this range “126.96.36.199/24”.
We will keep this thread updated with the latest developments. If you face issues while accessing websites or mails hosted on this subnet, please get touch with our Support help desk with the ‘traceroute’ result and your ISP details so that we can check it further.
Apologies for the inconvenience caused due to this.
