The occasional speed test the last couple of days has had fairly good results, but I still experienced a 2-3 minute delay resolving cse.google.com yesterday. Anyone else still experiencing this issue?

It seems that when this happens it affects multiple services simultaneously; if I get cse.google.com stalling on one website, I'll experience stalling on i.crackedcdn.com accessing the Cracked website as well, or www.google-analytics.com on another site, and they all start responding again at the exact same time after a few minutes. It doesn't appear to be DNS related as I've experienced the same thing using the Vodafone DNS servers as well as a third party.

This has been happening for a similar amount of time as the congestion issues so I thought they were probably related, but it looks like this might not be the case. I probably find this more annoying in general than the speed issues... trying to go to a site and finding that one of these Google/CDN addresses is stalling, and having to do something else for a few minutes until it sorts itself out.

Can confirm that it's still happening here. Hadn't noticed simultaneous instances but i'd agree that several minutes of no throughput is worse than slow throughput

gbwelly: Thread's pretty quiet. Are most people fixed but scared to call it in case it doesn't last? I'll stick my neck out and say I am on day three of having an awesome, fast, low latency connection.

My connection is fine... not perfect, but it's what can reasonably be expected when it seems nearly everyone in New Zealand decided to ditch TV for Netflix. Latency is consistently good even if my speed drops down to about 60-70Mb/s around Netflix o'clock.

I was talking to someone about this.

It seems the physical side is ok - or so it seems thanks to all those speedtests. However we still see those stalled connections.

I wonder if this is the good old Vodafone proxy farm interfering again.

To help clarify it would be good for those finding this problem to check

- are you using the Vodafone DNS for cable or a third party?
- does it happen when using the Vodafone DNS for cable?
- does it happen over a VPN?
- does it happen when accessing a SSL-enabled website?

Please excuse mobile formatting.

- are you using the Vodafone DNS for cable or a third party? Third party
- does it happen when using the Vodafone DNS for cable? Yes, just as bad
- does it happen over a VPN? No (astrill)
- does it happen when accessing a SSL-enabled website? Will try and remember to check later.

This is effectively the fault vodafone passed off as congestion until I got a tech to remote access my machine and agree it wasn't, got the logs through to complex team who said no fault (so it's expected a page on a 100/10 connection takes minutes to load?).

To be fair JaniceL asked me to provide logs again, I'm just over babysitting this connection and not in the mood to rerun cables direct to modem and spend an hour producing the logs all over again. but it's still better than adsl and my lease on the property isn't long enough to make fiber worthwhile.

Exactly having the same delay issue. I hope voda can fix this. I suspect this is with their proxy. My resolution was to setup my own proxy server at home and viola, no more delay issue. But I would still voda resolve this issue.

It could be their proxy is trying to do some scanning and delays web browsing.

Island Bay, 100/10 cable, standard DNS settings, no proxy:

Latency normal day and night, local and overseas. Nice.

Speeds 100/10 Wellington, Auckland, Sydney, Melbourne up to 7pm.

Downstream speeds in the 60s at 8pm and 9pm, local and Oz.

Upstream speeds OK.

Pretty good for a Tuesday 9:15pm - browsing with no lags, no waiting for Google properties, etc:

We're feeling a bit of congestion here. The speed tests starts out at around ~30-40 Mbps, but pushes its way upward towards the end.

There's also a lot of fluctuation in latency, and some YouTube videos take ages to begin initially loading (but once they start loading, they're generally fine).

In a few years, rural broadband should provide a more consistent experience. :D

The links off to the speed test server have limited capacity and are getting smashed generally by Gigatown users so your actual test results could be skewed

Plans are in place to expand the capacity but this is not a priority at the moment

Could this explain why Vodafone speedtest (http://wellington.speedtest.vodafone.co.nz) results are sometimes "slower" than the VF server on OOKLA (https://www.speedtest.net/)?

Here are my (Island Bay) TrueNet 100/10 cable stats for the last two weeks.

These are all hourly averaged stats over a 7-day period.

The last week in September:

The first week in October:

Nope.... it is the same server. But Vodafone haven't configured their settings on the local flash instance correctly. Need to tweak a few lines to get it working like speedtest.net

Smelled like a little latency earlier in the evening but at this point on our 50/2 things are looking pretty good:

Just off the four Aves, Central Christchurch - in work hours, morning, afternoon, evenings - pretty much the same results still:

Speed Test - Near Central 4 Aves / Chch

12 open tickets, 6 months, no responses to any of them, 3 manager promises of call back, - no call backs. Still waiting.

To quote Bobby Bare ( https://www.youtube.com/watch?v=ZytltN0cp_k ) "I'm worried now but I wont be worried long".

We have just arranged the transfer of 8 businesses's connections and phones away from Vodafone (as well as the phones for two other businesses) . Working on a further 10, as well as the phones etc and then we will look at the rest of our clients.

Voting with my feet.

PS: Oh - Vodafone - last time I raised a question on Geekzone re an issue with RBI connection, asking if there was anything I might have missed, you phoned my boss and tried to get me fired. I forgot to mention that we also moved RBI connections from you as after 12 months of sub 1 Mbps and no support your RBI down mid canterbury sucked!!!. Actually still sucks, over subscribed, outages, under performing sites - try firing me now.
