Confirmed connectivity issues reported.
Our report from the incident is as follows.
Loss of connectivity from some ISPs to our legacy IP ranges.
The duration was 9 minutes.
A large volume DOS attack (300Gb per second 200 million packets per second) targeted a single customer.
Our monitoring probes immediately reported the attack. Despite the attack being targeted at a single customer, the volume affected all our customers causing high levels of packet loss.
The issue was resolved by the automatic activation of our Level3 DOS mitigation platform. From start of attack to mitigation - the total time was 9 minutes. Our dDoS mitigation platform is a new addition to the Sonassi network to offer an unprecedented level of protection to customers - and we are extremely happy that a DOS attack of such significant volume was mitigated so successfully.
