Afrihost New Network Feedback - Part 2

Status
Not open for further replies.
One second I see 16ms latency to Durban, the next over 80ms. On the third hop for me, switching to another ISP and all is well.
 
I tried now with an IS based account. Not much difference. I knew and know its our exchange which is wasted.

Even the telkom techies know it. It appears regional telkom management doesnt care and is waiting around for their pension, doing the bare minimum work wise.

So AfriMan dont worry. Nothing and no one can save us in Harties.

That's odd, as far as I know we only started peering at NapAfrica when we moved over to our new network late last year.

Maybe I need to get a better idea of what you are pointing to. Can you mail me the results you are comparing on [email protected]?

My reference to mweb's and optinet's networks is related to the general poor performance everyone gets when anything is routed over their networks not in relation to when Afrihost started peering at napafrica.

What is much more interesting is why afrihost customers get such vastly varying results depending on where in the country they are.



(1) For example, if I was to do a trace route from my exchange ( Die Wilgers in PTA) I get a 9ms response to bras.afrihost.com, yet in other parts of the country, other gets results that seem to never be better than 32-34 ms and worse.

(2) Why do I get 13-14ms when tracing to afrihost.com (190.93.242.183) and others never get better than 32 - 34 ms (and they seem to end up on 41.86.112.68)?
(3) Why do we all get 32-34ms or worse when tracing to afrihost.co.za? Surely afrihost.co.za (41.86.112.68) should resolve to the same IP address as afrihost.com?
(4) If afrihost peers with others' at napafrica at Teraco in JHB, why not elsewhere in the country also?
(5) Why do afrihost customers show such varying results depending on where in the country are, and, why, if one takes the results I see in the Wilgers exchange area of 9 ms to your Bras server, does my friend in the exact same exchange area experience such poor results, which have consistently been blamed on "exchange congestion"?

All traces that involve afrihost.co.za end up going via mweb's and optinet's networks. Both of these networks consistently show erratic performance when benchmarking their DNS servers. Hardly ever do both networks DNS servers ever show no packet loss .....

From my side whenever a trace route involves these two networks there is a consistent 22 ms extra latency involved at best, and much worse during high traffic periods. It does not matter which websites are involved, if the routing is via the above networks, performance is bad, so why does Afrihost route anything via these networks?

This looks very bad. :eek:
It would be interesting to see the results if you ping bras.afrihost.com with your Telkom account.

Not sure what's changed in the last few weeks but by line speed is now slower. Where I used to get 3.6Mbit actual speed, I'm now only getting 3.3. Has something changed?
 
Nothing has changed. My speed is constant. :)

So last Satturday my line whent dead and I reported it,, on Thursday a Telkom tech came to my house and fixed it, well done to Telkom techs for coming out on a public holliday, the problem was someware between the pole in my yard and the next one up the street.

I was about to go away for the long weekend on Thursday when the tech came and was kind of in a hurry. After he fixed it I just listened for a dial tone on the phone and quickly looked whether the modem syncs, then he left and I was also out the door.

I came home just now and I'm seeing some reduced speeds.
Before the line broke my modem showed current rate around 0.9 MB up and 8 MB down, and it showed max rate around 1.2 up and 8.7 down.
Now it shows current as 0.5 MB up and 6.3 MB down, and max rate as 1 MB up and 9.2 MB down.
SNR was previously always around 6 dB both up and down, now SNR sits at 19 up and 6 down.

So seams my SNR improved from 6 to 19 dB after the fix or doesn't the upstream SNR really matter?
Also, why don't I get close to the actual speeds I got before, especially upload is concerning, it's half the speed it was before. Why do I get much lower current speeds even though my router shows much higher max speeds?
BTW I'm on a 10 MB line, surely this can't be ASSIA yet?

im convinced your torrents are shaped ... always horrendous speeds

The last week I am having the same problem. Was sent to Telkom from the Afrihost side. Contacted Telkom and they see no issues. Line became better and speedtest is fine and everything works fine except all torrents are downloading at 20-30kb

Exact same speeds 30kbps...

After hours full speed. So if I leave my torrents to run overnight they will be done in the morning....

So afrihost... Just give us the truth regarding torrents...

Its ASSIA and Telkom ass-shafted me precisely the same way.
 
Good morning Afris

Last night my line was feeling a tad slow but I ignored it and went to bed. This morning I checked and the line was syncing at 1Mbps (I have a 4meg line). Who do I need to PM to get this sorted?

Who is managing your line? Telkom or Afrihost?

:(

Exchange congestion / issues on the Exchange are incredibly frustrating. I hope you don't have to wait too long for the issue to be resolved.

That latency looks like may start on the Exchange already, could you maybe post a traceroute with the Telkom account so that I can compare the two.

When you ping bras.afrihost.com, that basically resolves to your Exchange, someone on the same Exchange may get a different result because they are further away from the Exchange or have a line that's poorer in quality than yours.

Afrihost.com and Afrihost.co.za resolves to the same site in the end, but the routing is different, this is more for redundancy than anything else. There shouldn't be much of a difference in terms of latency, and this is something we are investigating.
