终于开心了



During the past three weeks we have been experiencing a much larger than usual Distributed Denial of Service attacks against some of our customers. These attacks ranged from 30-50Gbps and caused some service disruptions in both of our data centers.  

Our policy has always been to attempt to help all of our customers to the best of our abilities. Unfortunately, these attacks caused some packet loss and service disruption ranging from few seconds going up to a minute.

While the methods we have used in the past have been successful in mitigating these large attacks, some large attacks are no longer manageable under the current policies. While DDoS attack sizes have increased exponentially on daily basis for the past decade and the network technology world has been able to keep up with new hardware, unfortunately at the moment, the technology is lagging behind.  ;

We understand that as a customer in most, if not all cases, you are not responsible for these attacks nor are you able to police the size of the attack you might receive. We had to take strict measures to curb the effect of these attacks against our entire network and the rest of our customers.

As of today, 12/03/2012, if any customer receives a DDoS attack higher than 10Gbps with certain attributes that might affect our network performance, the target IP(s) will be Nullrouted (blackholed) and the customer will be put on a monitoring list. If these attacks continue for a period of time, the customer will be notified and will be required to leave our network. Please be assured that we will consider all possible solutions before we ask a customer to leave our network. In accordance with this, we have already asked several customers to leave our network and have noticed much better performance on our networks as a result.

We have started work on a new major network update to our infrastructure in our Chicago data center to increase our network capacity. We will announce the progress of this project within the next few weeks and will then schedule the upgrade.

Thank you for your continued business and if you have any questions please feel free to open a Help Dest ticket for our sales department.
