Int speed for me but JHBAnything going on in the southern suburbs Cape Town? Noticed my internet was running slow, turned off everything, came back 30 minutes later, turned my router and fibre back on and it's still running like poop. I don't mind slow international speeds during peak times but 8 local and less than 0.5 megs international? Not cool. My line is 20/20 @TheRoDent @PBCool @CoolChick
Thanks I saw image posting that he's also got problems, and we're definitely in the same area. Wouldn't be surprised if we're like, the same street or something

I take it Octotel?
Please give us output of
iperf3 -u -R -b 10M -p 17001 -c trcvmh01.cisp.co.za --omit 2
Also, for all distressed Octotel users, trcprx01.cisp.co.za port 3128 is available to deal with packet loss. Configure your browser. This is purely a stopgap and workaround, but all I can offer at this point.
Seems to have recovered mostly now

That's still pretty bad. What does a -B1M (1 megabit look like) to trcvmh01?
Note: My download has had no packetloss, just upload which these iperf tests show. 80M included for sanity.

The -b is actually the bandwidth the client or server will send as a maximum, so it always needs to be below your line speed. [edit] Read your post again, you clearly know how this works, but perhaps do a 1000 packet size[/edit]
Can you do a reverse (download for me as well, will just be interesting to see as it seems directly opposite to what everyone else is reporting).

iperf Done.If I keep the buffer size below MTU (+ overhead), I can test for max speed as you can see. By default it will use an 8KB buffer, and for that I would need to keep some overhead open, 80M seems a good number, but I have seen some users (with 100mbit download) get almost 0 packetloss up to 92M with the default buffer size.
Yup, I'm on Octotel. First time using this, but speeds have also returned to normal. Hope it was just a glitch in the system and not a peak hour congestion issue.

I'm afraid as per lots of feedback tonight, that the "peak hour" congestion has returned. Talking to the Ops Manager at Octotel tomorrow. Again.
Not even sure if it's a peak hour thing, but something is definitely busted. 00:20 and look at these international speeds. This is wired btw.
Upload is now 'clean' again to local server
