Dear Customers,
We have been destined by a large DDOS attack which first resulted in a few time outs in our networks and we null routed the source quickly.
There was another DDOS attack destined us right after that which was large enough to take down the whole datacenter network and caused a 55 minutes outage in our networks.
This attack has been investigated and null routed as well and we have restored the network completely.
Attack Start time: 23/12/2011 15:06 (GST)

Dear Customers,
Our upstreamers was able to determine the source(s) of attack and placed a null route on them in order to prevent those illegitimate data transmissions passing into our core networks.
As a result, the pending /21 block of IPs that we had to denounce has been re-announced and our customers may now access their servers through those IPs.
Please contact us if you experienced any sort of difficulties while using your services through a support ticket or phone call.
Thank you for your patient and understanding and we truly appreciated your cooperation with us during the hard times today.
Thank you.
