Using Telkom ISP on Openserve. Since last weekend I have experienced slow international download speeds. It improved during the week and has again gone downhill this Friday. Is there a known issue with Telkom international capacity? Is this related to the Red Sea cable breaks? Testing with my Afrihost mobile data did not provide the same poor performance.

It might be loss on your line, a little bit of loss will cause poor performance on high latency TCP based connections.
Also, Afrihost uses openserve/telkom for some of their international transit so Afrihost customers would have also noticed an issue if it was a telkom issue.
Try running pingplotter to queen.cisp.co.za or lon.hosted.co.za or whatever server you are seeing the bad speeds from.

Happy to pop you a test account to try, at least should give you an indication.
Just to clarify on the above Telkom buys from Openserve, even though Afrihost does as well. They also use Liquid to a higher extent typically.

During the week I had no issues with international services that I streamed. What I have noticed from all the speed test, it is only the download speed that's performing poor. The upload speed is always at the full line speed.
I would like to take you up on your offer of a test account. Was not aware that you can use other accounts on a fibre line. Used to be able to do that in the days of adsl.

Sure thing, dropped you a PM.
Yeah you can switch accounts and ISPs on Openserves network.
The majority is Openserve as transit but there is a difference. Openserve is now offloading transit to 3rd parties for their customers like Afrihost which means it hops over to Openserve > Angola Cables and in some cases Angola Cables offloads to China Telecoms.
Openserve does not do this for Telkom. Telkom traffic strictly stays on Openserve network and if it needs to leave it goes via their Tier 1 transit.
You can see below the difference.
Some examples. Reverse from https://lg.nl.novoserve.com/

Honestly I think Openserve is doing this because its too expensive to upgrade their pops vs just leveraging someone like Angola. I wouldnt be surprised if they migrate more traffic that way over time.
Those aren't major ports sizes for the modern era.

That is exactly what it looks like. They probably got a sweet deal from Angola.
The problem is if you complain to them they just say but your traffic is carried without loss to and from the destination. They never guaranteed that the traffic will be exclusively on their AS. Their supported communities also doesn't allow you to prevent this. They can offload your traffic on cheap transit at their discretion.

Look as a transit provider this is very much the norm, they would still buy transit somewhere as they did before.
And it is still via their "AS"
These are unfortunately the restrictions in using local transit providers, your only choice is to try work with them. If you cant get to a point where you are happy then you need to go shopping for an alternative provider.
