Citylink's official Debian mirror (ftp.nz.debian.org) is apparently
again broken (not even listening on port 80 from where I'm sitting).
Would anyone be seriously interested in donating rack space, national
transit, or hardware to the cause of another official Debian mirror for
Having reliable and cheap access to free software projects like Debian
is critically important, and having a second official mirror seems like
a no-brainer to me.
I am very happy to donate my time to admin and monitor any equipment
provided for this, and to liase with the Debian project as required.
Perhaps Citylink could give us some insight in to the traffic levels
their existing mirrors see?
Does anyone have any suggestions for how to investigate what looks like
certain paths of inter-virtual-router layer 3 switching (routing, via
routes leaked into the VR) on a Juniper EX4600 (and I'd guess QFX5100)
being sent via the supervisor CPU? Searching online turns up lots of
advice for investigating, eg, "process switching" on Cisco (eg,
but I'm not finding much documented for Juniper :-(
From the customer point of view the most obvious symptom is
approximately 10-20 ms additional latency on a local routed path (VLAN A
on VR 1 to VLAN B on VR 2), but apparently only in one direction (ie, if
we bypass the EX4600 in the problematic direction then it "seems to be
okay". It happens even when there's basically no traffic (eg, under
1Mbps on a 1Gbps link), and only a couple of dozen devices on each VLAN.
(At times we've seen the latency as high as 1000+ ms -- so over 1s,
for local traffic -- but that was at a busier site.)
From an internal point of view, the most obvious symptom is that the
forwarding-options analzyer shows ingress/egress on one of the VLANs,
but only ingress on the other VLAN; and "monitor traffic ..." shows only
the missing egress traffic. Since I'd understood "monitor traffic" to
only see traffic that goes via the supervisor CPU, I'm starting to
wonder if the latency is coming due to the packet flow in that direction
going through the processor CPU -- for some unknown reason.
This is happening at two sites, but they're basically identical EX4600s
facing basically identical switches, and equivalently configured routing
instances in each. The two VLANs are sub-interfaces on the same
aggregation (ae1) to the same switch, so it's sort of hairpinned, but
via leaked static routes in the two routing instances. The on-VLAN
hardware at each site is pretty similar too. So we're guessing the
cause is the same, but don't know what it is. We've already tried
testing with the aggregation down to a single link, and it appears to
make no difference. We've also forced ethernet flow control off at both
ends, without making a difference.
Any thoughts, particularly to see what path through the EX4600 packets
are taking, welcomed. Or documentation for how the EX4600/QFX5100
packet forwarding engine architecture works (I can find M/T/MX
documents, but not the one I want...).
The National Library of New Zealand is looking for an experienced Digital Preservation Web Engineer to lead its web archiving programme.

* drafting a business case for indexing, search and delivery for the Library approx 80Tb of web archives.
* contributing to the development of the strategic direction of the National Library with particular emphasis on the Library's digital (web) collection building, preservation and access roles.
* working closely with national and international peers, related teams within the department and with external vendors.
Working at the Department of Internal Affairs, you'll have the opportunity to make a real difference in the lives of New Zealanders.
The National Library of New Zealand sits within the Information and Knowledge Services branch, the Department's epicentre of information management. Our branch is all about collecting, storing and preserving important things that are precious to New Zealand.
You will have substantial practical experience in an IT environment with specific emphasis on web framework technologies and protocols, and preferably also demonstrated experience in web archiving. You will be a self-driven specialist, ideally with a tertiary qualification in information technology, computer science or information science or its equivalent.
This role also requires you to be legally entitled to work in New Zealand.
If you want to join a team of smart, committed people who do spectacular work for New Zealand - then this might be the right job for you.
Applications close: 5PM, Friday 28 October 2016

The NZNOG organising committee invites papers for its 14th annual
conference, to be hosted at Trinity Wharf, Tauranga, New Zealand
from 23 - 27th January 2017. There will the three day Workshops 23 – 25
January, a day of tutorials on 25 January with the main conference on 26
– 27 January.
The NZNOG conference, workshops and tutorials are a once-a-year
opportunity for individuals and organisations involved in Internet
operations to meet and share the latest in Internet operations,
technologies practices and receive high quality training.
The event is unique in New Zealand and attracts technical, skilled
individuals with a genuine interest in Internet operations and
Submit a paper:
Presenters are invited to submit abstracts of their paper for
consideration by Monday 28th November. Abstracts should be no more than
one page long and provide a summary of your networking-related subject
To submit your paper please e-mail: talks(a)nznog.org
When considering a presentation, remember that the NZNOG audience is
mainly comprised of technical network operators and engineers with a
wide range of experience levels from beginners to multi-year experience.
There is a strong orientation to offer core skills and basic knowledge
in SIGs and to address issues relevant to the day-to-day operations of
ISPs and network operators in the conference sessions.
Note: The inclusion of a title, bio, topic, abstract, and slides with
proposals is not compulsory but will help us determine the quality of
your proposal and increase the likelihood it will be accepted.
The organising committee will evaluate proposals based on fit with the
conference’s objective and its ability to stimulate lively discussions
around the current state of New Zealand networking.
