Title: slow speeds during evening and night time.
Post by: neil on March 24, 2020, 06:40:43 PM
Hi,

I am facing this issue of high pings packet loss and slow speeds during evening and night time everyday. Is it only bandwidth issue of my local MSAG or is there issue from local exchange? How i can check it?
All i can stream is YouTube in 1080p without any issue. But other websites and downloads are very slow as low as 50KB/s for downloads. Speed test shows slow speeds to international server and high pings.
Everything starts coming to normal after 12am-1am at night.

That sounds like Congestion either a hot SVLAN i had this issue before with BT about 2 years ago they could never find the cause of the issue so i managed to leave without breaking my contract. But since i went back to them it seems to have sorted itself out since they upgraded my green box with a extra one for more lines. Mine use to happen around 11pm and would go back to normal around 3pm every night if you got a good ISP maybe they will be better at diagnosing the issue.

This is what I found to what refers as a "Hot SVLAN" it means there is congestion of the network bandwidth that customers share from your cabinet/exchange. I'm still learning from my experiences when it comes to this soo only take it as a pinch of salt I'll leave it to the more experience Kitzens here but when you mentioned slow downloads in the evening it sounded exactly what I was getting 2 years ago apologises if I didn't explain it clearer I'm still new to all this myself but with the Kitz forum it's teaching me a lot and with my personal experience.

CVLAN -- Customer Virtual Local Area Network
SVLAN -- Service Virtual Local Area Network

So in case of BT as nfxcr3w said, is the problem in that case be related to BT as a service provider (ISP) only? so other ISPs (WBC) may have a better service, or this "VLAN" (do not know what it should be called) are using the same one "or same BT equipment" so in that case all ISPs will have the same problem as BT.

We must remember that Neil lives in Pakistan. So there can be subtle differences in service provisioning from that which we are familiar, be that of Egypt or of the UK, for example.

This guy is in Pakistan so I'm not sure we can transpose experiences in the UK to him.

If YouTube is okay and everything else is not points to a capacity issue out of Pakistan to the rest of the world, not helped by testing to Islamabad off peak and Paris at peak.

Stick to one server for testing.
Check other forums for if there's a capacity issue out of the country as a whole.

No, we can't. Our network is arranged in a certain way and we have no shortage of capacity out of our country. Many countries in the world do have a shortage of capacity going international.

when my isp was installing msag i heard them saying, subscriber card capable of supporting 64 numbers. Is that what you guys are calling Hot SVLAN?

Nope.

I heard YouTube has local CDN that's why no problem for it

why there is shortage of bandwidth for international traffic? If I may ask?

Essentially, it all comes down to one word: Money. That spent, in the past, on the infrastructure and that currently available to spend.

There is also potentially the incentive to keep users using local services, if they make international ones perform poorly.

There are probably dozens of points where there could be congestion.

At your MSAG. Where multiple MSAG's point back to (the exchange in our country). Connections between Cities.

Connections out the country may be affected, but not necessarily all of them. Traffic to Asia might be fine but traffic to Europe might be congested.

What CarlT suggested try testing to the same servers, some inside your country and some outside.

thank you for reply. The issue is not slow speed or pings during peak hours. I understand there is limited bandwidth, But the issue is packet loss for games in the region of Europe and USA. It feels very laggy and movement in games start stuttering. Ping is only increased by 10-50ms.
