Incident type: DDoS attack
Our monitors picked up that Edge 2 was not responding as expected and was dropping traffic, an on-site network engineer was dispatched to investigate the issue. On analysis it appeared that the issue was not with the edge switch itself, but with a targeted DDoS attack that had avoided detection by our systems. Once this was apparent we enabled DDoS mitigation for the relevant end server restoring the edge switch to full service.
We are currently reviewing our DDoS monitoring with a view to updating it to automatically catch this new style of attack.
