The root cause is a DDoS attack against Binary Lane, large enough to be toppling Superloop’s network.

“BinaryLane is responding to a large-scale denial-of-service attack targeting our entire autonomous system.

The attack has been significant enough to affect our primary upstream provider, who has had to drop our ports several times to protect their wider network — most recently because the attack resumed each time we were re-added. We are currently announcing traffic via our secondary upstream, which is keeping the platform reachable but with reduced throughput and higher latency for traffic outside Sydney, where the secondary provider’s footprint is concentrated.

We have a meeting at 4:00 PM with our primary upstream to agree a sustainable path forward, and in parallel we are working with another Australian carrier (with whom we have direct connectivity in all our DCs) to bring additional capacity online for mitigation. Customer data is not at risk — this is a network-level attack, not an intrusion. We’ll post a further update immediately after the 4:00 PM meeting. Thank you for your patience.”

It seems there is slow headway towards resolving this impact:

“Servers are only accessible via IXPs at the moment, which means they are still not accessible via Telstra/Optus/Voda/TPG/Superloop and most international ISPs at the moment. The techs are still working on fixing it.”

Superloop has confirmed this outage to their network, stating:

“We are currently experiencing a service disruption affecting the INDIGO West link due to instability.
Our team is actively investigating & working to resolve the issue.
Updates will be provided as information becomes available.”

INDIGO West is a 4,675km-long cable system offering direct, low latency connectivity from Perth to Singapore.
Binary Lane (Mammoth Media) leverages Superloop for most traffic, so are between a rock and a hard place.

We’ll consider any post-mortem outcome and changes before evaluating whether to relocate NS1 instances. At this time most services remain entirely uncontactable. We will relay all updates received. Thank you.
