PSD Group Engineers identified a DDoS attack aimed towards a single customer IP, which was coming from a large number of external IPs. Steps were taken to BlackHole traffic on our primary transit link. A further attack has been observed this morning (towards the same IP), on our secondary link. Further steps have been taken to mitigate this and traffic levels are now returning to normal. The customer who is being attacked is taking steps to identify the possible source, whilst their traffic remains blackholed. Engineers will continue to monitor.

Engineers have observed a recurrence of the DDoS Attack towards the same customer IP as yesterday. We have taken steps to proactively mitigate this traffic and traffic levels are returning to normal

Engineers are seeing small amounts of packet loss on some customer circuits. Engineers are monitoring

Engineers appear to have identified a denial of service attack (DDoS) aimed at one of our customers. We are working with the customer to get this resolved.

We’re aware of issues with connectivity for some customers. Engineers are investigating and a further update will be posted shortly.

Engineers are still observing brief periods of packet loss, all be it less impactful than earlier. Works are continuing to investigate the route cause.

Engineers observed a drop in connection and subsequent port flap to one of our BGP Transit Peers. Users experienced a short period of packet loss whilst links re-converged back and forth. All transit links are back online and stable and engineers are continuing to monitor the connection.
