Tiket.com was DoS attacked
 The attack was for a whole month!
 Attack technique changes every time we mitigate:
• TCP attack
• DDoS attack
• Slowloris attack
• SYN attack
• Slow HTTP request
Ticket.com was using another global cloud for everything
from Web servers to database servers and load
balancers. In spring of 2012, they were heavily attacked
by a black hat hacker using several methods, including a
TCP attack, UDP attack, slowloris, and ultimately DDoS
using hundred thousands of open proxies.

Tiket.Com Selects Softlayer as IAAS
Partner for Total Peace of Mind
Tiket.com approached SoftLayer to resolve the
downtime they were experiencing, moving its load
balancer to SoftLayer and adding 1 Gbps bandwidth
to a robust high-performance bare-metal cloud
infrastructure – delivering a superb customer
experience in the process!
