Looks like CISP is oversubscribed...

Possibly!! Although I first brought up my international upload woes in August 2017 so it might just be the nature of the network...Looks like CISP is oversubscribed...

I'd like to participate in these tests as well because I experience ( on most occasions ) the same thing as @requiem . In the mornings or very late at night ( after 11pm/00am ) international seems to be fine, but during peak time ( 6PM - 11pm ish ) it goes to ^%$&&^$&^$, and this is exactly the time we need it to be 100% ( or as close to 100% as possible ).
Like I said before - it all has the symptoms of congestion/contention on the international portion of my line because local it is always 100% full line speed - never have an issue here.
Need to get to the bottom of this and see where the bottleneck is, because it is not worth paying for 100 if all i'm going to get out of it is 10% of that.

I was under the impression this was resolved after swapping out your CPE? If we have any international issues we would post it and be straightforward about it. If we have no issues then we need to go through diagnostic steps to put forward to the layer2 provider.
Haha at least you are paying for 100mbps, we pay for 200mbps and sitting with like 10mbps speeds during that period
I think Cool Ideas really need to resolve this issue, as I see more and more people are complaing about the same issue during the same period of time.
No it remained the same, it improved the latency about 4ms though, but again internet speeds would drop intermittently usually from 6pm to 11pm... and on certain days the connection speeds are so bad I get like 3-9mbps to international servers... then I cannot stream anything (apart from youtube which is cached locally).
But to give you a more exact numbers, it feels like my connection gets capped to 30mbps to international servers (london, frankfurt, new york) from 6pm to 11pm, it wont go anything above that. During the day I would get about 100mbps to these servers, which even that is 50% of my line speed, so never really see speeds above 120mbps to international servers even when everything seems to work fine, only when I test to local Randburg speed test I get 204mbps and nowhere else I see anything close to this.
In a nutshell my connection feels like driving a ferrari at 8am or 5pm on the highway between Rivonia and William Nicol![]()
Definitely not Cool Ideas that is "over subscribed" more like there are a few areas where the Fibre operator is oversubscribed or haven't got the capacity out of the area which is resulting in slow speeds during peak times to international locations
If everybody was having the same issue then there would be ALOT more posts on here lol.
If there is any packet loss on your link which is either due to a fibre issue or contention at peak times (which seems relative to what you are describing) somewhere on the network, this then has a major effect on international or higher latency traffic due to re-transmits.How can it be Vumatel if my speeds locally are perfect but only international is fubar

Try again?@PBCool
I'm not sure if its just on vumatel in cape town, but the routing that is taken on sacs differs to what the core network is doing in some instances.
Example, this is what the return path should look like:

But its doing this:
View attachment 569773
Is it possible if you could change this?

Just as bad as LTE then. From 6pm - 11pm is completely slowI'd like to participate in these tests as well because I experience ( on most occasions ) the same thing as @requiem .

If it was contention - why is local traffic not affected - or do you mean contention on the international portion ?
As mentioned because re-transmits on local traffic happen that much faster compared to anything higher, therefor the local traffic "wins" when contending for capacity.If it was contention - why is local traffic not affected - or do you mean contention on the international portion ?
