So I'm using the following script to check our sites to make sure they are

"down" when, in fact, they are actually up.   These sites do not require a

this be due to some port being blocked internally ?  Only one of the sites reporting 
as down is "https" but all are internal
sites.  Is there some other component I should be including in the script ? 
 There are about 30 or 40 sites that I have listed
in all.  I just use those in the following script as examples.   Thanks

import urllib

I've never used urllib, although I've done a fair amount of network 
programming at lower levels.

Are you sure the report of "down" isn't simply a time out due to the server 
being busier than you expect when you hit it?

After adding the line suggested by Larry, I was able to determine that the URLs 
reporting as "down" were actually sites
requiring authentication in order to provide site content, so adding that 
line to the handler was at least enlightening in that
respect.  Thanks Larry.

Glad to help. Here is some info on authenticating with urllib:

It must be a network problem, cuz your code works fine:

:w !python
http://www.amazon.com/
http://google.com
http://tobiah.org
http://notavalidurl.com
http://superreallyforsurenotavalidurlnokidding.com is down

This worked perfectly.   Thank You


Where, exactly in the script would I place the " print str(e)  " ?

The line after the print site + " is down" line.

I'm not really receiving an "exception" other than those three sites, out
of the 30 or so I have listed, are the only sites which show "is down" at

If your exception handler is being called then you are indeed getting an
exception. Add:

print str(e)

>From your description, I'm unsure whether it's *only* the HTTPS sites
that are having issues, or a subset of your URL list that includes
both HTTP and HTTPS (where those sites happen to be internal).

Either way, my first suspicion is that you have some sort of proxy
server in your network that web-browsers use.  The urlopen() accepts a
parameter to list proxy server information, which you should be able
to glean from your browser settings.

If your web-browser isn't using a proxy, the sites might be doing
unsavory things like filtering by user-agent.  Dumping the contents
of the exception (and including it here) might help diagnose.
