Unable to get to specific websites via ISA Server proxy

I have been running ISA Server 2004 for many years without issue as a web proxy.  Starting about a month ago, users are unable to get to a couple of specific websites:

http://csllibrary.org/
http://www.cotesaintluc.org/en/welcomepage

I can get to them fine if I go directly out via my gateway, but if I go through the ISA, I get error:

Technical Information (for support personnel) •Error Code 10060: Connection timeout
•Background: The gateway could not receive a timely response from the website you are trying to access. This might indicate that the network is congested, or that the website is experiencing technical difficulties.

When I was first troubleshooting this, I blew away the urlcache (which had not been done in a very long time), and the problem was fixed.  The issue is back again, and this time deleting the cache did not solve it.

These are the only 2 sites that are having this problem.

Any ideas?

Thanks!

ever tried accessing some other pages (rather than the homepages only) of the two sites especially those with basic HTML?

be aware that today is in 2015 and a 10+ years old web proxy server might not be able to understand all HTML coding nowadays.

There are many possible reasons for this error.
Check your NIC configuration according this article:

You can also try to increase timeout:

I just increased the timeout in the registry.  I would have expected a reboot to be necessary before it would take, but before doing so I tested the sites and they are working now.  I guess it is just a coincidence.  We'll see if the sites stay working this time.

Thanks for the responses.
