Nate

I am not being difficult.
I simply will not participate in whitewashing through solving one person's issue at the expense of others.
Orcon clearly have big issues with their network. There hasn't been a week without an outage.
So not sure how my details could lead them to a eureka! moment.

Sounddude may be trying to do some kind of a job, but to suggest that response routes from google are routed via LA (as this was his explanation why google went down when the LA link was affected) is silly. Anyone who will suggests or believes that a packet route Sydney -> LA -> Auckland takes 35ms (when the packet actually comes back) is dreaming.

There is something more wrong here.
If Orcon were based in Christchurch you'd still hear "It's because we are still affected by the earthquake" as an excuse.

This is tonight's traffic:
...
--- www.facebook.com ping statistics ---
35 packets transmitted, 19 packets received, 45.7% packet loss
round-trip min/avg/max/stddev = 167.764/170.369/206.179/8.454 ms

...
--- www.l.google.com ping statistics ---
31 packets transmitted, 19 packets received, 38.7% packet loss
round-trip min/avg/max/stddev = 33.603/109.158/1443.033/314.398 ms

And I could go on.
So, what's the cause this time. Any guesses?

Is that is from a Orcon ASDL connection provided over Telecom wholesale?

My guess (I'd put $$ on it) is handover link congestion from Telecom wholesale.

Unfortunately there is practically zip nada zero Orcon can do about handover link congestion as it's a Telecom wholesale service dimensioned at rates specified by the ComCom determination.

If this is the case, then only real solution is to change to an ISP with less congested handover links (one with a better balance/ratio of low usage users to high usage geeks).

This has nothing to do with Telecom congestion.
I can get national everything at full speed.
I know it's easiest to say it's Telecom, but it very rarely is.
This is Orcon's "routing issues" (which by my suspicions should say Sandvine, routing issues don't simply appear in high-usage periods and then go away), as already reported by Quentin in a different post:

You kept blaming it, so I thought you knew how it worked.

(08 December 2010)

cdn.store.steampowered.com and computerworld.com not loading (Yet again), with google.com and youtube.com the latest websites failing to load.

The bandwidth/network upgrades mentioned on the Network Status page should have been completed by now, I'd imagine.

PM'd sounddude... He reckons my specific issue is a provisioning fault. Sounds slightly ridiculous. Has yet to confirm that it really is a provisioning fault.

Certain sites do work with a DNS change, some sites do not. In my mind that is a routing issue.
Will have to wait till sounddude PM's me back with more information I guess.

dauckland: Hi there.

As I understand (was told) this issue is because of recent changes Orcon made to their Sandvine appliance.
So as we know this is all to do with very intensive shaping.
This is done in different way depending on one's connection being Orcon purple or telecom wholesale.
The difference is: 10-fold increase in latency for some international sites that pass through 121.98.104.2 (i.e. www.google.com)

D

things also get pretty crap when they go through asianetcom.net what enters at ~18ms seems to gain 125ms which just compounds the problem when more hops are required

C:\Windows\system32>tracert www.guru3d.com

Tracing route to guru3d.com [85.12.17.135]

Athlonite:

The Round trip between USA West Coast and NZ (for a packet) is approx. 80ms IIRC (40ms each way via the Southern Cross Cable). Consumer grade traffic 'delays' the packet a little, hence the ~125ms round trip latency addon.

(10 December 2010, ~6am)

Google hosted websites and steampowered.com Sydney CDN working again.

xmarks.com (Bookmark sync service I use) stops working, with tracerts timing out right after ge-0-0-4-0.cre1.nct.orcon.net.nz. Still haven't heard back from sounddude.

Seems like Orcon's international traffic is being routed via different (internal) links - 121.98.9.1, 121.98.9.130, 121.98.9.134 and 121.98.9.13. Found out by performing a tracert on multiple websites hosted internationally such as cdn.store.steampowered.com, 8.8.8.8 (Google's public DNS server), bigpond.com.au and xmarks.com.

Internal load juggling, it seems. 'Provisioning fault' seems very unlikely, too (routing issue).

Hi Redskt

We have seen your type of issue before, if the correct profile hasn;t been added to your account. This profile dictates what MTU, and billing profiles are used.

However, yours seems to be correct.

Can you confirm what MTU your using?

Hi Sounddude,

I'm using MTU of 1500 on my Windows XP machine; OS default values on other machines.
Also xmarks.com is working again.

Thanks.
