Line speed becomes snail pace in the evenings?

+6 votes

My line has usable normal speed up to 5 pm every day, where by it starts slowing down untill it is 400 kb/s, and returns to normal in the morning. It slows down at almost the exact second that the time reaches 5pm,7 days a week, I could set a watch by it. Also during rain, it doubles in both speed and signal qaulity.

this occurs normally at times your exchange receives/transfers high bandwidth usage.

this is caused by internet users accessing the internet most frequently on those times.

if you have a little extra cash to spare, try upgrading your line speed.

Defo not shaping, 400 kb/s ???? I think Telkom is a much better answer. Here's a tracert anyways to

That looks like packet loss to me, ask Telkom to reset your port - might work

Hi there :)

Generally, the sort of congestion you have reported is as a result of low port availability and congestion on an exchange level. Your individual line works very well and the stats look great, but the exchange itself could be overloaded.

This results in fluctuating speeds, high latency and occasionally packet loss. This would affect all lines connecting on that particular exchange. The reason it happens predominantly at certain times of the day is because, it's the time of day that a majority of the connections in your area are being utilized. This is also evident at nights, and over weekends when there are more users on your connection.

A residential area is usually going to be affected during early to late evening, and fine during the day. If there are a large number of businesses and home offices in the area, daytime usage would be affected mostly.

Ultimately, the only way to permanently resolve this would be for Telkom to upgrade the capability of the exchange you are connecting to. This is unfortunately, not something that can be requested. Telkom follows their own upgrade and modernization schedule, and are most likely already aware of the congestion on that exchange.
