FierceGuppy:  For example, 100 people downloading 100GB at 100Mbps is likely to cause more congestion than 100 people downloading 10TB at 20Mbps.



Not quite.

100 people downloading 20 TB per month is roughly 100 x 33Mbps per hour sustained traffic throughout the month. If there were hypothetically 100 customers downloading 10TB that's be 3.3Gbps of traffic just for them, which in itself would cause an impact across a DOCSIS platform.

100 users downloading 100GB per month wouldn't be continuous traffic - even if they were bursting to 100Mbps it would be momentary traffic, not continuous. It's sustained background traffic that's the real killer here - whether that be torrents or somebody watching HD video feeds 24/7

You can't allocate a CIR of 30Mbps per user to sustain that sort of throughput and deliver a service at the sort of price that our unlimited plans are.

You'll see plenty of posts from me last year predicting 2014 would be the year we could start to see price increases for unlimited plans because increased traffic usage wouldn't be sustainable. I think we're a little closer to seeing that actually happen.

I'm pretty sure the congestion is due to ISPs taking onboard more customers for whatever service and more customers buying more services or moving to faster plans while network upgrades have lagged far behind.  Prices are going down.  In fact, yesterday I looked at the no-cap package I have -- unlimited, cable/fiber, home phone.   It's dropped $18.  Had better call Vody about that one.

If everything on-net (ie to the VF speedtest server) is OK, and its other destinations that are congested, that suggests it is nothing to do with the cable network and everything to do with the upstream connections, surely? At least as far as problems today are concerned?

VF speedtests are affected.  Yesterday I started this thread when I got 14Mbps from the Christchurch speedtest server.  I was experiencing Twitch.tv stream buffering problems and that was when I throught to do a speedtest.  This morning before work I got 111Mbps, an hour ago I got 89Mbps, and now it's 78Mbps.   6:50pm 24Mbps.

Vodafone is also a Netflix partner and have a Netflix CDN in their NZ Data Centre. So I'd expect any issue with streaming Netflix on Vodafone will be outside of their network (apart from Cable) - i.e. Chorus handover, DSL1 connections, trying to stream over Wi-Fi etc.

Dratsab:
sbiddle: ...potentially Vodafone need to look at ways of dealing with the small number of customers who (if what I've heard is true) are using 10+ TB per month on residential plans. I don't believe for one minute anybody doing that could justify it as legitimate usage. 

If that's true, I'd imagine Vodafone will start to look at implementing a fair use policy for their cable network.

If that's true and it is causing issues (even if just exasperating other issues) I'd hope that Vodafone would have already implemented their fair use policy!

Wonder what one does to be pulling down 10+ TB/month...
