Hi all.


Everything went very quiet after the VLan segmentation implementation(s) went ahead on Telstra's cable network.

I would mention that to the best of my understanding, it was a multistep and on-going upgrade, involving hardware and software -with the nodes under most pressure being upgraded first.

annectodally, I have to say that at some point there was a definate improvement (here in Wellington; Wainui) and as most people observed, the activity light on their cable modem stopped "strobing" which seemed a likely indication that ARP traffic had indeed been significantly reduced (over the network).

I definately noticed better stability, with less dropped games -but lately I've started dropping out again.

After a week or so of this, I ran some Ping tests against the default gateway (again) and it confirmed my suspicions.  Every few minutes or so, I'd get a delay that was long enough that the Ping command would actually timeout.  This was very typical of what was happening originally, and these intermittent timeouts definately correlate into being dropped from any online games I might try to play while the newtowrk is behaving this way.

Quite honestly, I pretty much just accept it these days, and go watch a movie, or do something productive.

But I'm just putting it out there -on my node at least, service has definately started to go down-hill again.

Yep, me too (in Khandallah). Of course, no word from TelstraClear on the issue.

This is what I'm all too used to seeing lately. Curiously, it seems to only occur on international sites. At least that's what I've experienced. Come on TelstraClear, tell us what's going on!

This message has to do with something I've been complaining for a while, even posted here before - but no one believed it was happening - for some time now.

My take: TelstraClear is using a transparent proxy and it is badly configured, badly performing.

I have not been able to stay in any online games for more than a handful of minutes before I get dropped.

Has been that way for the last few days.

ps Although I'm describing a different problem, I would not be surprised if it is somehow related.

The fact that Pinging the default gateway is producing such irratic results (anything from 9ms up to a few hundred and then a complete time-out) tells me there is something wrong at Telsta's end.

I'm not sure if it simply some sort of overload of resources, or configuration issues.  I'm hoping the latter, as I think there is more chance of things getting fixed if they do not have to spend more money upgrading gear.

If you're meaning for cable there are other options. I don't know an exact current number but there are other ISP's who offer cable services. This solves some of the issues such as the apparent issues with the transparent proxy since the traffic takes a different route from the headend.


Just going back to your earlier post it's quite common for routers on the int3rw3bs to drop ICMP traffic if they are under load. A ping test isn't a definative test to know where, or even if, packets are being dropped.

Point is I've managed to discover a clear correlation between time-outs on the gateway and dropping from online gaming sessions.

When the Ping times are consistent, it doesn't happen.  When I get timeouts, I drop everytime.

Are any of these providers likely to offer a residential plan for someone living in Wainui?

I'd appreciate a list.

Thanks.

ps.  As of just after midnight last night the Pings to Telstras gateway smoothed out to well under 20ms response times (with the occassional ping slightly over 20ms).

Suprise surprise I didn't drop from a single game.  As of this morning, the pings appear to still be OK (with only the occassional one going slightly over 20ms):

...

So Steve, if your comments about dropped packets (I assume while I'm pinging the gateway) is a normal/reguler/expected event, then why do I get sustained periods (like several weeks of it before things started acting up again) of such fast responses (from Telstras gateway)?

As far as I'm aware, by pinging the gateway, all I'm doing is knocking onTelstras front door.

Last I heard there are still 3 ISP's who offer cable connections. Xtreme networks are the most popular but as a residential customer their plans would be of no interest. I'm unsure who the other two are.

It potentially does indicate a fault but not receiving a reply to a ping isn't conclusive evidence as it is common for routers to drop ICMP packets. Hopefully the problem might now be fixed!

Just check down the cable provides here, but in short, ADS, Telestra in both paradise and clear guises, and Xtreame, pretty much outside of TCL plans they are buisiness ones.
