Obviously the cache fill that happens between midnight and mid-day consumes some
bandwidth, we find the fill capacity (after the initial fill) is about 1.2gbps for on
average 2-4 hours per day.
We currently share our cache on Megaport IX Auckland, in doing so we find we’re filling a
few other providers caches so they don’t have to fetch it from AU, so this may be helping
Our cache currently uses anywhere from 100mbps during the day to 1.6Gbps at night, but as
mentioned we are serving those peering on Megaport IX free of charge.
I have attached a snapshot of our graphing from 26th 6am till midnight which seemed to be
a big day, please excuse the graph blip from some planned work on the observium server.
On the backhaul side of the network, we haven’t seen a large increase as clients were
already netflixing via VPN’s or Bypass methods so it was a simple move of traffic from USA
to NZ instead.
I observed via http://monitor.nsw.ix.asn.au/cacti/graph_view.php
that iiNet, M2 and a few
other providers picked up an extra 20-50% of traffic the week of Netflix going live.
What I consider may be an issue is lots of unlimited ISP’s had an average of how much
traffic clients would be using and limiting P2P traffic to ensure legit traffic got
Now that Netflix is used during peak times and providers would have limited backhaul
around the country; the increase in traffic will not be an increase in revenue (due to
fixed unlimited prices).
ISP’s are probably a little more reluctant to upgrade their backhaul links when there is
no additional revenue (hence optus and iinet wanting to charge netflix), or such upgrades
can take weeks or months to do.
I wonder how Chorus ‘tails steps’ are affected where chorus are backhauling traffic from
around the country; chorus may be seeing some congestion though we’ve seen no evidence so

Following recent media articles making mention of "the Netflix effect"
and broadband slowdowns at peak times, we've had a number of requests
to see if we could pull together some facts from NZ ISPs detailing
what they are actually seeing.
So the question is...
How much Netflix/SVOD traffic are you seeing, either as a direct
measurement or percentage of total traffic.
Does this percentage change at all during the day/week.
I realise that this may be considered commercially sensitive but I'm
sure we can find a way to make it work.
If you're happy to give number on the list that would be great. Good
on you for sharing.
If you're not comfortable with that then drop me a line and we can
discuss how you might feel more comfortable about sharing the facts.
I'm happy to agree to only give an aggregated number from people who
contact me privately for eg "ISPs are seeing between X and Y % SVOD
Or you could just tell me and I'll keep it to myself (not quite as
helpful but I can use it for context).
You could also tell me "we have no way of knowing" and I guess that's
a data point too :).
