We are current experiencing some intermittent network issues, Senior staff are aware of the situation and we are awaiting further information from the datacentre.
Thanks for your patience.
Update 3: All systems online, an RFO will be sent in due course.
Update 2: Please see the latest Update from the DataCentre:
The initial problem with a peering point that occurred earlier this morning has led to a problem within the VSS routing cluster. Our network team quickly eliminated as many causes as possible. This issue was then escalated to Cisco and we are currently involved in joint investigation to try and discern the underlying problem. As soon as we have any progress from this work we will inform you immediately.
Update: We have confirmed this is an issue with our upstream and will send a full RFO in due course.
