Service: Impact to WAN Connectivity
Impact: Loss / Degradation of Services to Customers
Incident Details: On 17th March at 15:10 we experienced an influx of calls from our customers as they were experiencing difficulty in connecting to our services. We were also alerted by our monitoring solutions that there was an issue with WAN connectivity to our Maidenhead facility.
Progress Details: Our initial investigations confirmed WAN connectivity to the Maidenhead facility was at fault and therefore we immediately liaised with our Datacentre partner Pulsant. Pulsant were already aware of an issue affecting one of their Internet Access partners.
At 15:20 on 17th March our Datacentre partners confirmed that service had been restored, resulting in a maximum of 10 minutes of disruption.
Corrective Action: Pulsant has confirmed to Quest that one of their Internet Access Providers experienced a DDoS (Distributed Denial of Service) attack.
The threat was promptly identified and engineers removed the threat from the affected links as soon as possible.
Additional Comments: A DDoS attack is an attempt to flood a network with traffic in order to make that network unavailable to the intended users. This is not an attempt to ‘hack’ or access data, but merely to render the access to that data unavailable. At no point was the integrity of data held within our facility at risk.
Our clients experienced a range of outcomes during the 10 minute window of the incident which ranged from excessive latency (a delayed response from the system) or total loss of service.
Whilst Quest regrets that the incident took place, Quest is satisfied our Data Centre partner and its upstream suppliers took extremely prompt action to restore service. This swift resolution to an intelligent DDoS attack is testament to the benefits of utilising a Cloud solution and a world-class Datacentre Partner.
