1. the SK data center Firewall filters out a bandwidth of 50 Gbit/s. If the server is attacked, the firewall automatically responds and maintains all ports properly. Attacks of less than 10 GB will not slow down, and server ports will not be blocked. The server is in the security protection status. When the server encounters a DDOS attack, the IDC firewall automatically responds to the attack and implements real-time protection, only the attacked IP address is blocked in an extremely large data center (the attacked IP address will automatically return to normal after several hours), and other IP addresses will be used normally.

2. rich IP resources. each server has 61 independent IP addresses and unlimited traffic. it is the largest unlimited traffic data center in the United States.

3. convergence of five major ISP operations in the United States optical fiber access (He. net-10Gbps, XEEX-10Gbps, XO-10 Gbps, TISCALI-10Gbps, VERIO-10Gbps), BGP4 Technology anti-attack firewall, the largest free anti-attack machine room in the United States.

4. the operating system is free of charge. the computer room provides a fully-qualified Windows 2003 standard operating system for free, and the redo system is completely free of charge.

5. SK data center is not sensitive to complaints. it is a good choice for customers who are often complained about.
