Some advise will be greatly appreciated,
I have a 4mb ADSL line with Afrihost, running a business 4mb account,
I seem to always have a problem at night during 6pm and 11pm with international speeds, always ranging from between 50 - 80kb/s
First I thought it was congestion on the local DSLAM, however local speeds run full during this time.
I even get the same speeds using an SAIX or IS account, could congestion impact only international speeds?,
as far as I can see from trace routes and pings everything is in the normal, local 20-60 and EU 180-190.
It's very unlikely that various ISPs would be affected at the same time, as most use different international cables and routing. If there is local congestion, it would affect international traffic. If it's mild enough, local traffic may seem OK but international traffic will experience higher latency and slower throughput accordingly.
Can we see those traceroutes?
