Had a few issues on the changeover from Snap but the email support was great and suited me 100% as a hardcore geek. I reported the issue at 10:12am, first reponse back from support (who had already talked to Chorus at this point) was 10:34am - all sorted at 12:05pm.
Initially the upstream seemed to be limited to 100mbit, I was busy with other things and wanted to get more examples before contacting support. Before I got a chance to do any more on this, I noticed a few PPPoE drops on Thursday morning around 5am and now that restriction is gone:


Even further afield I am very happy with - if speedtest.net ran a longer test when the latency is high I think TCP Window scaling would do it's thing and higher speeds would be achieved:


The only things I'm missing from my old ISP are static IPv4 (though I realise it will be hard/impossible for new ISPs to offer this) and IPv6 (good for my own education and experimentation).
Great work from everyone at Bigpipe :)
cheers
