Hi Everyone,

I have a problem that comes and goes with bandwith usage. With a demo of Network Probe(Objectplanet software) I can see what the traffic is that hits the NIC of the pc on which it is installed. I can pick up some epmap traffic which is incoming from washington.edu domain ip's but even when these are not active we still experience slow links.

I tested ping for ip and name and some local sites in South Africa don't even resolve!? So would I be correct in presuming that it is possibly not as much a traffic problem as a DNS server / or upstream ISP problem?

we need more. precisely how are you defining 'slow link'?
do you experience random periods of slow web browsing? are you using vpn and have users complaining random periods of slow performance? you cannot see a correlation between amount of traffic and this problem? then there is none. imho. can you reproduce this? can you log it to look for trends in time of day or whatever might present itself that way? do you have your router on a battery backup? (try doing that).
what are the particulars of your network? how do your users connect to the internet. what is the os of your network clients? do you have proxy server? what is the os?
not clear to me if you know that not all sites allow ping? and not resolving via ping imho does indicate a problem?
do you think others on your isp experience this when you do?
did you always have this problem or has it cropped up recently? what has changed?

Tracert is a better tool for internet speed problems than ping.

Tracert will give you time factors for every addressable device you go through.
