Morning, some customers who use our hosted VM Fortigate firewall in Manchester will have seen issues getting online this morning. The incident occurred at 9:50 am and was fully operational again by 9:58 am.
Our Networking team identified this as it was happening and have noted that the CPU had spiked to 100%, this has since dropped back to operational levels and they are investigating what caused this.
We are very sorry for any inconvenience this will have caused to affected customers.

Following the Network team's investigation, the root cause of the CPU spikes was down to a DDoS attack on one of the customers hosted behind the VM Fortigate Firewall. The DDoS resulted in 1 million packets a second hitting the VM platform, causing a temporary spike on the CPU. The customer of the targeted DDOS has been contacted directly.
The DDoS has now subsided and our Network team will return to monitoring the network as usual.
