Resolution: We have identified this was a DoS attack on our nbn, vdsl2 and ADSL ranges from an International source. Our network mitigated this attack and we are working with upstream carriers to identify the source.
1545hrs AEST: We are now resolving this status update, we are looking further into the cause.
1502hrs AEST: Traffic is normalising and we are seeing services restore to their full performance. We are monitoring the situation and ensuring that it does not return.
1425hrs AEST: We are working on what the issue is, some parts of the network have now improved but we are still seeing performance issues on particular paths to other networks.
1345hrs AEST: We have identified some performance issues on some of our IP transit links and we are investigating the cause. Domestic peering is fine so cloud services such as Office365 and Google should be working properly.
