We are currently facing some issues on the network of Linux Server, the datacenter has informed us that they are facing some DOS attacks on their network and hence the servers are appearing as inaccessible, they are in the process of null-routing these IP's with the upstream providers and the situation should be back to normal shortly.
Our helpdesk is fully staffed and our team members are working with the Data Center technicians to get the situation under control at the earliest.
We regret any inconvenience caused in the process and expect your kind co-operation as always.
