Incident Date: 25/10/2019
Time of incident: 13H22
Length of incident: 20 minutes
Please note we experienced a DDOS attack on our network which started at 13H22 we do have DDOS protection systems in places and a scrubbing service, implemented in our UK data centres.
The system automatically takes measures to protect our network. As these measures are implemented the attackers modify the attack to bypass the automated thresholds which we then need to manually tweak on the protection system to block and clean the traffic. We have seen an increase in attacks in the last few months.
The network did experience a brief performance drop while we were modifying the DDOS migration thresholds, performance on the network was fully restored by 13H42. The network is performing as expected and we will continue to monitor.
