Some pretty appalling trans tasman pings tonight. These servers are normally half that.

Seeing some packet loss on those first two AK border routers, seems to have settled down now but at one stage hit 30% on the first one..
Highest ping to the first server spike at 185.. and it's normally 40-50ms (which is 119.252.191.193 btw, just noticed that missing in the winMTR text) 

There is just no way I should  be seeing an 100+ average spiking to 185ms ping to Equinix Sydney!

Not that anyone form Spark apparently cared, but it's back to normal tonight.

I've been having this issue all week between 8pm and 11pm. Its never normally this bad.

Spark tried to tell me its not their problem.....


Appears to be this server: ae7-10.sebr4.global-gateway.net.nz [122.56.127.214]




History of conversation with Spark:


Oct 5
**Advised Spark of issue **
@SparkNZ are any issues with NZ to AUS bandwidth at the moment? My latency to Sydney is shocking.

**Reply from Spark**
Hi Sausage, no issues we're aware of. If it's a particular server, please DM results of a traceroute test and we'll have a look^DB


**Sent back**
@SparkNZ thanks for the reply. It had an 80+ ping for all traffic to Sydney/Aus til about 11pm 5/10. Then it came right, back to 25/30 ping. Happened last Monday night too. Ill run speedtest across the week and see if I can nail down when it happens


Oct 6

**Sent tracert**
Ok its started again tonight as well to all Australian servers. No issue for local traffic at all. Its never been this bad before.

See here: http://s13.postimg.org/h35715pon/Latency_Issues_to_Sydney.png … Here is TRACERT output: Tracing route to http://ns1.telstra.net  [139.130.4.5] over a maximum of 30 hops:

Oct 7
**Spark Replied**
Hi Sausage. Thanks for your message, the results looks fine for NZ connection and issue is at international gateway which unfortunately is beyond our control. Cheers^VN  


**Replied with slightly annoyed tweet from me about their customer service being different to when I worked for Telecom years ago**



Oct 8

 

**Spark Replied** Hi Sausage, I'm not sure what domain you've looked up there, but the end IP of the tracert (139.130.4.5) is hosted and controlled by Telstra in Australia. We can send this for a further look, however as VN stated, as it doesn't point to a fault within our network, there may not be anything that can be done. Could you confirm the domain and/or type of server you're contacting (i.e. is it a particular game's server?) ^DB

 

**Sent back** Hi thanks for the response. The issue is to any server in Australia. The bottle neck is this server: http://www.ip-tracker.org/locator/ip-lookup.php?ip=122.56.127.214 …

It's being looked at. It may not be an issue in our network. Also, so far you haven't given any indication about whether throughput is affected or if you have observed any packet loss. You've also only done a forward path... Sometimes for [reasons] the forward and reverse paths can go different ways, and one way might be a lot longer than the other way.

This is often outside the direct control of the affected ISPs and in many cases doesn't represent a fault.

It looks like something is going on that isn't optimal, but it doesn't look to me like it's a simple case of a congested link. There's no ETA on a change or improvement to the behaviour.

Too many people on netflix? :0

The worst I've had to Australia previously was maybe 60ms during peak time, now its half again or double that to any server.

I don't mind if it's something out of Spark's control but at this stage I'm assuming that the 'global-gateway.net.nz' Spark servers are NZ side so wouldnt expect the ping to be 80ms to get there....



Will take a look at packet loss and try reverse trace route when it occurs again between 8pm and 11pm tomorrow. Seems to be all good again now.

You are missing the point. Even if it looks to you like the problem is in place X it might not be. You haven't looked at the reverse path at least.

Also... Netflix is having approx zero impact on our international traffic at peak times.
