[AusNOG] Fibre Cut in Sydney - Vocus

[Luke Mackinnon]

Hey All,

Vocus certainly has diverse fibre from the Alexandria CLS too, always has. Happy to help customers out with diversity if they want it, always will.

In this case the issue isn’t the a lack of diversity in the Vocus fibre network.

The real issue is that if you buy an unprotected or single drop service from Southern Cross then you only get one customer facing port from SX, and if you do not have your own DWDM (or equiv) at the CLS and you bought/lease (rely on) dark fibre to extend your SX circuit from the CLS to another location, that singe dark fibre circuit off of the single SX customer facing port is always going to be a single point of failure and a risk.

Vocus and many of its customers survived the outage as we implement an architecture using 2/3Drop Restored capacity from SX meaning that we have diversity from both the Alexandria and Brookvale CLSs. It is unfortunate that some do not have the benefit of the same design in their networks, there is always a cost benefit trade off, unfortunately cost often wins.

I would be more than happy to have a deeper discussion on the benefits of the Southern Cross and Vocus networks that can be leveraged to avoid issues like that we saw on Tuesday, if anyone is interested please feel free to contact me directly.

Cheers,
Luke

Pipe had diverse in there and as Superloop are now buying some SX capacity
and landing Indigo nearby we are building diverse paths in as we speak.  Happy to help anyone out if they need diversity as in end of April.

Cheers

Hello David,

Yes, Vocus may have been operational however several Telcos and ISPs in the pacific islands that use Vocus backhaul with their termination points on the Equinix SY loop suffered major outages. For example, Digicel Pacific (in Fiji and Vanuatu) had major network outages with no international voice or internet as a result of this fibre cut. Vocus may have been all good, but their customers certainly were not. What diversity does Vocus have in place from the CLS in Alexandria to the Equinix SY loop?

You do realize that Vocus have no control over companies with side boarers right? Its that company obligation to do dial before you dig.

And you do realize that Vocus was still operational with their diverse links right?

Also you know that Vocus was not they only one to suffer from that cut right? SCCN and other carriers did as well.

I don't think it be fair to target them on this occasion.

Cheers,

David.

No not really, this is Vocus we are talking about, the same company who
had an entire DC go offline during a maintenance window.
I know technology and infrastructure fails from time to time, but Vocus
have not had a good run at all the past month or two.
