WEB SITE ACCESS SPEED

Answer

QUESTION

I'm having trouble accessing your web site and/or downloading files. Why is access to your web site so slow?

ANSWER

Internet access is always a strange thing. Between our web server and your computer are a number of machines that we can't control. If one of them is slow, then that whole connection is slow. We realize this is an important issue, and we have taken a number of steps to address it. For example:

If you continuously have problems, try running a trace route on the connection. If you have Windows95 or WindowsNT, the tracert program may be found in your Windows directory. To trace a connection, enter the following command in a DOS box:

TRACERT  www.keil.com

This will trace the route from your site to the Keil Software web server. It will appear similar to the following:

traceroute to 206.50.62.12 (206.50.62.12) from moose.erie.net (208.138.204.11), 20 hops max, 40 byte packets

After you get to our firewall, ping requests are no longer accepted. Note that one of the networks we interface to is Verio, so if you get to d1-12-0-0-22-0.a02.dllstx01.us.ce.verio.net, you are one hop away from our network.

You may want to contact your Internet Service Provider to see if they have any suggestions on how to improve performance.

Our statistics indicate that the best time to surf our web site is between 7:00pm and 11:00pm Central Standard Time.
