We have seen the Dunedin-to-Invercargill link fail, while the Christchurch-to-Dunedin link was still being repaired. As a result, this has isolated the DUD and TOD PoPs from the standard REANNZ core links. These two PoPs are still reachable due to our emergency core link to the area, however this link operates with reduced capacity. We will update again within 60 minutes.

The fibre fault has been identified as rodent damage within the rail corridor. Repair work will continue tomorrow.

Now seeing that the issue has been identified as Double Fibre Cut taking down both redundant paths servicing Dunedin.

Path 1 cut between Dunedin and Oamaru
Path 2 cut between Gore and Balclutha

Seems odd to have both go at the same time, I'd have thought.

Nothing showing on 2degrees, One NZ, Spark or Chorus pages about any outage, despite hundreds of reports - somehow - on Downdetector.

I work for Foodstuffs in Invers, mate at Finance now here, another at DHB here, they both had nothing. I had Internet but lost access to some systems. And now tis slow, good to finally know why

If you have to run heating in winter, you don’t own enough computers.

The information I have is that the damage has occured to a cable owned by OneNZ between Gore and Balclutha. Technicians have been dispatched by OneNZ to investigate.

This has caused the loss of 3 Regional Transport and 4 Backhaul Connect services.

The views expressed by me are not necessarily those of my employer Chorus NZ Ltd

I've been in a MS Teams meeting since 11am in Dunedin and didn't notice a thing. On Slingshot

Slingshot = Vocus = 2degrees, which has been fine apparently.

Our 2D connection is playing up so have failed over to backup fibre connection.

We're rural Oamaru.

Opinions are my own and not the views of my employer.

[Identified] Trains have been stopped and techs allowed into the tunnel to start repair on the first fibre cut. ETR will be late this afternoon. The location of the second fibre cut between Gore and Balclutha has been identified and techs are enroute. Engineers are attempting to restore connectivity to some of the impacted cell sites by rerouting traffic to a different network path.

[Identified] We have received a tentative update describing when restoration of service to our isolated Dunedin region might occur. The supplier is targeting based on their current understanding of the fault a resolution at approximately 1400 this afternoon. With one link restored network service will resume at full capacity, but with jeopardy remaining as we await the second fault to also be restored. This we also have reason to believe will be completed late this afternoon.

Ww have a site in Invercargill, and one in Dunedin.

Dunedin site went offline at about 1030, both the Fibre and backup LTE connection. One NZ told me the Fibre was OK (they said they could see the ONT), leading me to believe that it was our CPE at fault. I was preparing to book a flight and go into the office and grab a spare security appliance and fly to Dunedin. Staff on site mentioned that their Spark and OneNZ mobiles weren't working (2D was). I started suspecting it wasn't our CPE. Staff then told me that neighbouring businesses were offline too, then an article appeared on ODT. We had the LOS light on the ONT green for a while, It's red now.

LTE came back, though very patchy, at about 1330. Lots of packet loss, and high pings. Fibre is still down. This is in Central Dunedin (George St).

At least I'm not on a plane, but it's a bit of a cluster when it all goes down.

Back in the "old days", multi-pair copper cables were wrapped in cotton, impregnated with arsenic, to keep rats away.

Bitrix was/is used to stop kids drinking things they shouldn't.

Is there no equivalent that can deter rats chewing on these fibre cables? Must be some money to be made by an inventor here.
