After confirmation from Datacenter, we know our one server which name is ” ROZA “ it’s down and we try to fix our server ASAP. Datacenter confirm to us this server is down for NULL routing. Somehow and by any chance our any client tried to make illegel activites with there hosting and its track by datacenter or DDoS attacks are detected therfore datacenter stop our normal opertion. Using this, the server can be temporarily disconnected from the Internet to prevent harm to the entire infrastructure and bandwidth over-usage for a particular server. We already contact with them and the work with the issue and we hope it will be fix Soon. Please do patience.
