I get responses from Google referring me to a known, existing web
site:  "www.berkoradio.com" and several variations thereof.  But when
I click on any of them, my computer replies, "no web site configured
at this address."  This is the website of a well-known newspaper and
radio financial columnist, Malcolm Berko.  What's going on?  Thanks.

Hi there fbell2.

Unfortunately, it appears that the website you refer to is currently
not online. The message that you are seeing, is being sent by the
computer which formerly hosted berkoradio.com. There are a number of
possible reasons why this might be the case, including software
configuration errors by the site's programmers; non payment of their
web hosting bill; or just that they're in the process of updating
their content.

The result that Google is showing you is the snapshot that Google's
software took of the page, as it visited it. This may well have been
from many days (or even weeks) ago.

In situations like these, there are two fairly easy ways of taking a
peek at the website as it was before it went offline.

1) Use Google's cached snapshot.

Simple put in the page address that you wish to visit into the Google
search box, click Search, and if Google is currently holding a cached
copy of the page, it will offer to show you this.

2) Use the WayBackMachine, run by Archive.org. They maintain a large
snapshot of the web, dating back to 1996 in some cases. You can see
its cached copies of berkoradio here:
http://web.archive.org/web/*/http://www.berkoradio.com

The chances are that the website will return fairly soon, so keep
checking the page for updates.

I hope this helps, and if anything's unclear, then please don't
hesitate to request clarification before rating this answer.

All the best,
