Michael D. Posted February 15, 2011 Report Share Posted February 15, 2011 We've been alerted to a large DDoS attack that is hitting one of our customers on the Cypress server. The attack is in excess of 1 GBPS (1,000 MBPS) and as such has been null-routed. We're still investigating to determine which site is being targeted so that we can ensure that no other accounts on the server are affected. If you have any questions, feel free to post them here or to open a support ticket. We'll update you as we have more information to provide.

Michael D. Posted February 15, 2011 Author Report Share Posted February 15, 2011 The IP address that is being hit is shared by several accounts - we're splitting all accounts out to their own IP addresses so that we can identify which one is under attack. This is going to take some time and we will update you. Moving accounts off of the affected IP will also cause them to come back online - DNS caching can cause this to take an hour in some cases but generally it's pretty close to instant.

Michael D. Posted February 16, 2011 Author Report Share Posted February 16, 2011 All accounts have now been assigned their own Dedicated IPs and we'll be watching for a shift in the attack. Quote Link to comment Share on other sites More sharing options...
Michael D. Posted February 16, 2011 Author Report Share Posted February 16, 2011 The attack hasn't shifted off of the original IP and as such we're leaving things as-is until the attack fully subsides. Quote Link to comment Share on other sites More sharing options...
Michael D. Posted February 17, 2011 Author Report Share Posted February 17, 2011 The DDoS hasn't come back since the null route on the original IP was removed. We will be migrating accounts back to this IP address tonight (during off-peak times) to reduce any potential for downtime due to IP caching. If you have any questions, do open a support ticket.
