If you have any packet loss on your line any increase in latency will have an exponential effect on the throughput due to re-transmits taking that much longer.
Ah, thanks.

I presume the best way to check for packet loss is to use WinMTR - which host should I test to?

Still no feedback from CISP
Have asked a teamleader to contact you and do some iperf testing so we can see if there's significant loss.

I can backup the claim about packet loss. I have ~3% loss every evening on my line. That's enough to drop my 100mb line down to 0.8mb throughput. Its not pleasant.

Your best bet is to do iperf tests. I've found through my tests mtr doesn't always show the packetloss, iperf does.

@PBCool ... wow

so you guys cancel me on a Friday afternoon without notice and did not refund as we discussed. the hope was that if you cancelled you would refund me such that I could move to another ISP ... also

"Service is still with CI and service end date is 17.03.2019"

so means I can't even move to another ISP until you guys send that cancellation to Mfn which you did not. feels like a cheap ploy to just piss me off?

someone get in contact with me now please ...

And what might that be? Don't tease us!
Sorry for the silence, we let our customers know through our support channels and thought it would be best to refrain from sharing our findings until Octotel shared their report.

No network problems in my area according to CI's website. Anyone else in Randburg getting horrific international speeds?

Geesus, you and fibre?!! Just wasn't meant to be bro...
So I'm currently using Vodacom LTE roaming with my French contract which allows me 25Gb a month in SA for 19,99€. :ROFL:

By the way, I'm pretty sure of the answer but you are the person following me on Twitter and commenting on my fibre issues there as well, right?

That's cheap. If you were roaming in France with SA Vodacom it would be that for 100mb probably!!

Yes, that's me!! ;) Use my real name on twitter though as do you...
