List of congested exchanges?

[Flaming-Sheep]

The exchange in nearest to Edgemead, Cape Town has recently gone to sh**. In this past week my pings have shot up from 10-30 all the way to 300+ (Peaks at around 600 sometimes).

My line speed is also diminished, but that could just be me being throttled. I'm more worried about ping anyways.

[PseudZ]

I work in Bellville South. For the past week the speeds have been terrible, could this be a congested exchange or is it just IS that is causing problems?

[undesign]

I have a 4Mbps line for many years. Over the past two months it started to degrade to such an extent that I'm often unable to do a speedtest. Afterhours the line is unusable and I get worse than dialup speed. I have logged several calls with Telkom and currently have one open (17ATK270811) and povided them with the speedtest results from various days and times. Sadly they are not doing anything to resolve the problem.

I guess the only thing is to get enough of us to make our results public and then if we're lucky we might get them to do something. My modem sync speed and quality is excellent. Latency is good and I have no line errors or packet loss, but download throughput is shocking most of the time (below 300kps). Upload speed is not a problem and test at 0.4Mbps most of the time

Sounds exactly like my ADSL. Vierlanden, Durbanville. Currently getting 7KB/s...on a 4Mb line. Uploads at full speed. Couple of calls to Telkom, 4 times to the shop, 3 escalations (first two very friendly, 3rd one full of **** **** **** ****s), stopped a techie on the road. End result? NO RESPONSE.

Currently fantasizing about C4 and the exchange...

Currently considering this approach as well, as this seems to be the only solution to the problem really...

You can add the Somerset West exchange to the list. Think it might just be our DSLAM in our neighbourhood though. There seems to be a load of congested DSLAMs all over the place as well. (Too small a link to handle the traffic back to the exchange). The thing is congested as fsck! Getting 1000ms on average after hours and it starts claming down to about 500ms later at night and only returns to normal at about 11:30 - 12:00pm. I'm sick of this ****. Thinking about cancelling my ADSL, but only after giving them a little bit of uphill.

Are you 851, 850, 852 or 855?

Yep Bothasig Exchange has gone to s.it in the last 2 weeks, local ping times that was 50ms is now 500ms during the evenings. Need to start cutting random phone lines...

Easy. They on the same BRAS as you, but on a different DSLAM. Each DSLAM has it's own uplink to the BRAS. A single DSLAM can only take between 100-1000 ports. If its a dslam on the street then its gonna be closer to 50-100 ports.

wtf are you talking about. I'm on mweb 4mb uncapped, and live near beaumont primary

international ping - hetzner.de = 179ms
local pings - 196.25.1.1 = 11ms
google.co.za = 11ms

maybe its your ISP rather than your DSLAM

Ah I see, thanks this is very informative.

[pietmuis]

Zappers/Vindicator do you have calls open with Telkom? I want escalate this, maybe if we escalate multiple calls for multiple parties we have a better result... this is interfering with my game time!

I logged an online fault report, but haven't heard back from them....

[pietmuis]

Zappers I manange to escalate my call today and got a ref - not sure if it will achieve anything.

[grimstoner]

I just purchased a WebAfrica Pro account (I always use Afrihost) just to eliminate the possibility of my slow speeds being ISP related. It isn't (btw... getting better pings on Afrihost).

I assume then that my exchange is also congested. The slow speeds only started this month.

Anyone else on 012991xxxx? Think its called the Faerie Glen exchange.

Is a "congested exchange" something Telkom would fix?
