Hmmm.. I just went back to the site and it did come up properly, however,
pinging the site still fails.

This is quoted from: http://www.michna.com/kb/wxnet.htm

Cannot browse some web sites
Temporary Internet Files
If it is just one particular web page you cannot display or of which you see
only a part, it may just be the cache. Occasionally a mutilated, cut-off, or
entirely empty web page gets stuck in the cache, so first of all delete the
temporary Internet files:

  1.. Open Internet Explorer.
  2.. Click on: Tools
  3.. Click on: Internet options
  4.. In the block Temporary internet files click on the button: Delete
files ...
  5.. In the new dialog box click on: OK
It is not necessary to delete all offline content.

MTU
If you use the PPPoE protocol (or some other Internet link protocol that
requires extra header space), for example for a DSL connection using a
router or ICS (Internet Connection Sharing), you may have to reduce the MTU
(Maximum Transmission Unit) on the client computers from the default of 1500
to 1492 (or in certain circumstances even less), because the PPPoE protocol
takes 8 bytes away for an extra header. Some other protocols and routers
also require a reduced MTU, sometimes even much less than 1492 bytes.

Check your router and make sure it doesn't have a needlessly low MTU
setting. If your router has such a setting, try to increase it as far as
possible.

If that doesn't solve the problem, and even if it does, install Service Pack
2 at least on the ICS host computer, which should, in theory, fix the
problem. (Actually it was already fixed in Service Pack 1.) However, there
seem to be cases in which the problem persists even after Service Pack 2 has
been installed. In that case, please read on.

An elegant way to solve it is to uninstall your current PPPoE driver and
install RASPPPoE instead, a free, but excellent driver you can download from
http://user.cs.tu-berlin.de/~normanb/. This driver has excellent automatic
MTU discovery.

Another way is to change the settings on all computers, including all
clients. You can do that with the help of a small freeware program named
DrTCP, which you can download from http://www.dslreports.com/drtcp, a site
that also contains quite a few good explanations of the background for all
this, including explanations on how to do all this by hand.

You can check your TCP/IP settings by going to the web site
http://www.speedguide.net/ and look for Broadband Tools. They also have a
program similar to DrTCP, but their program is (as of 2004) quirky and
poorly designed.

If there are any doubts, reduce the MTU setting to 500 bytes for a test.
This is a value that should always work. If even this doesn't resolve the
problem, set it back to 1500. Your problem is not related to MTU. If this
does resolve the problem, try to find the largest MTU value that works for
you, usually in the range between 1440 and 1492 bytes.

For more details you can read the following Microsoft Knowledge Base
article.
