Network issues [Resolved]
Posted by Helpdesk Admin on 12 April 2016 03:41 PM

We've seen a significant slowdown on several services in the last few minutes, this is affecting email and web for some customers.

It looks to be a network issue, we are investigating and will update soon.

Update [16:05]

There is an intermittent issue on our network, we expect to last at least another 60 minutes.

Update [17:30]

We are seeing an increasing amount of traffic hitting our network at the moment. Working on this but expect at least another couple of hours.

Update [21:30]

We have had some progress in reducing inbound traffic but it appears to be a concentrated attack and all our fibre links are at full capacity at the moment. Due to the scale of this attack (200x normal traffic) we will need to mitigate this externally.

Update [13/4 08:00]

We have been working with F5 throughout the night to mitigate this attack. We are routing traffic through some serious hardware and we hope to have everything up and running around 9am.

Update [13/4 09:15]

The attack is still ongoing but is being mitigated fully since 8:45 so is not affecting services. All web services are operating normally however email is likely to be slow for a period while queues flush out over the course of the morning and while additional mitigation rules are put in place.

Update [13/4 12:00]

Mail queues are still slightly higher than normal but these will clear out over the afternoon.

Update [13/4 18:00]

The attack is still ongoing but is being mitigated so is not affecting services. All services should be operating normally.

Update [14/4 08:00]

The attack ceased yesterday evening.
