LATENCY!!!

P.S. IS ADSL in CT doesn't seem to peer on CINX (yet).

idk if this is relevant >> http://mybroadband.co.za/news/broad...single-cent-for-transit-anymore-MWEB-CEO.html

im starting to think there is more going on than meets the eye. obviously something changed and whoever is at fault for causing these bloody network issues is being very shady about the truth and trying to pass the blame or deny it all together.

i find it surpising that btwn mweb and telkom they cant pin point the problem or give us any answers. its time for a press statement. get rudi to challenge telkom directly. its time to throw some weight around, mweb. i pay my full line rental and isp to you, mweb. i only decided to do that because i though then i could get all my problems solved at one place. but... 2 months later and there is still no information about this issue. wtf?

Please post your latency (tracert is fine). We haven't had any from Plumstead/Wynberg for a while.

Fairly steady at 150ms in Clareinch almost the whole day...

Edit: We haven't had many SAIX users on this thread. Either they haven't noticed, or Telkom has a 'special router' for its own customers (wouldn't surprise me at all...)

I'm on Cybersmart, who I belive use SAIX. I'm getting the same issues, good ping <60ms early morning, and >150ms after lunch all the way to midnight. I'm on the West Coast, Tableview area. Tried different ISP accounts and same problem. Seeing latency on the 3rd hop using Tracert.

For what its worth I am on Rondebosch 9 according to Telkom

If you are on a different DSLAM, then the 2nd hop must be the ESR, somewhere upstream (I thought the 2nd hop was at the exchange). In any case the problem is always between the 2nd and 3rd hop, for all of the graphs on this thread.

Will: Can you plase confirm where the 3rd hop is located (logically and physically). If such a wide area is involved it must be either a Telkom router or MWeb's IPC?

A friend of mine in Camps Bay has just told me that he's started having similiar issues... chalk another one up
 
@ajules It's entirely possible that we are all on the same ESR.

Not our IPC no. If that was the case the problem would impact on all of our subscribers and I have done comparitive tests from here and on our testbench at the office which links to the Belville exchange and the experience is poles apart. I believe I posted some of those traces quite early on in the thread. Also we know that it affects multiple ISPS which also effectively rules this out.

As I understand it the portion of the network between the 2nd hop and our IPC is not visible due to VRF so the issue exists 'somewhere between the DSLAM and the ESR' and the answer to the million dollar question 'so where is the congestion' simply has not been offered up yet.

@ajules Yes it's entirely possible that we are all on the same ESR. In fact the original FQ that I logged when I started looking at this was to investigate possible ESR congestion.

@peTer The issue of paying for transit links between networks is not related to this. Improving transit relations and creating a freer and more open Internet is for the benefit of everyone. The issue we are dealing with here sits either somewhere on the ADSL infrastructure (Telkom last mile), or on their backhaul network which connects all the exchanges and ESR's together.
 
To keep me entertained during this crisis, I went out and bought a Playstation move and some other ps3 games!

Still need to get some multiplayer action though :(

I wonder if we will ever be able to game again :(

Anyways here's my latest graph http://www.imagehost.co.za/share-0252_4CC48462.html

Can you show a longer period graph (right click 12 hours). A 'flat-line' like that is highly depressing (and not too informative). Also right click on 'graph min & max' which shows jitter.

Edit: Also save as Gif, not Jpeg (its much better for graphs).

My truncated graph for today (rather depressing...) http://www.imagehost.co.za/image-608C_4CC487E1.gif

Edit: Thanks for the answer Will. I'm sure it must be as frustrating for you as it is for us...

Ye i know, I've got it running a 24hr now, just merely wanted to show the amount of packet loss
 
Two friends of mine who were lagging for the last 2 months have now stopped lagging all together. On Wednesday both of them said telkom called them and moved there lines to a diff dslam and now the lag is gone. They have not been lagging since then. The one lives in Plumstead and other in Wynberg. They both use Afrihost.

This makes me think that Telkom are busy upgrading specific Dslams and routing users to the Clareinch/Rondebosch until they are done. So maybe there is some light at the end of the tunnel.

The new Medal of Honour single player for me this weekend, was a bit short possibly, but very well made :)

I also played single player Medal of Honor this weekend. Not as good as MW2 though. But would really love to compare the multiplayer! Which obviously we can't at the moment :-( The only online game that is playable under these conditions is Farmville, and I'd rather be shot!
 
so what have we gathered so far...

the connection from our routers to the first hop is fine and the problem lies between there and the next hop. 'somewhere between the DSLAM and the ESR' apparently. the problem is linked to traffic congestion and is getting worse over time and affecting more and more people (presumably as traffic increases). throughput is being affected with speedtest results about 2mbps down (on a 4mbps account) which is possibly an indication of how over subscribed the network is.

11 August 2010> got automatically upgraded from 4mbps to 8mbps
12 August 2010> pings started creeping up

pings got higher and higher at first just in the evenings, and then more and more throughout the day. packet loss got worse and so did ping until it was crap for gaming 23 out of 24 hours a day - and completely useless for gaming 17 hours a day. its possibly still getting worse and affecting more and more people. packet loss is also on the rise at its worst levels ever now.

24 October 2010> the problem has persisted almost 2.5 months now, ive complained to mweb multiple times who said its not them, its telkom. ive complained to telkom multiple times who are acting like nothing is wrong and refusing to give me any answers or deal with my problem further (engineers dont even contact me anymore). they seem to be avoiding the problem and acting like it doesnt exist. there is still no official statement from them or any sign that they are actually trying to fix it.

here's my last 48 hours graphed... the trend is blatantly clear: http://i.imgur.com/oxUW0.gif

here's my speedtest results (4mbps line and uncapped mweb account): http://www.speedtest.net/result/1003144744.png


i tested 3 accounts: mweb uncapped 4meg, telkom monthly capped, and web africa prepaid. whats interesting is not all the hops after the first one bad in these cases. i dont know what that means.

Im in rondebosch east SO im probably on the crawford exchange 021 696 . and yes im having the same issues. Noticed on friday past ping was back down to 20ms even 10 at times but i guess that was due to the fact that telkomsa.net was down as i was on the fone with them and they confirmed they had a connections problem whole day. As soon as telkomsa came back online the Ping went to hell again. Been loggin calls with telkom and ofcourse the techies have no clue what im talking about. Will give someone a bit higher up a call today and hopefully stir the pot so that this can be at least looked at by them.

I would also sugest all you guys keep logging calls and explain to them exactly what is goin on. Techies will be going out to the exchanges today and tomorow , The more calls they have for the areas the more likely it is that they will see the problem.

Latency still tolerable at 9.30am (Monday). Based on someone's (?) graph from last week, it starts to rocket up around 10am.

Time to start monitoring please!
