[Will Sheppard]

User-Agent:       Mozilla/5.0 (Windows; U; Win98; en-GB; rv:1.8.0.6) Gecko/20060728 Firefox/1.5.0.6
Build Identifier: Mozilla/5.0 (Windows; U; Win98; en-GB; rv:1.8.0.6) Gecko/20060728 Firefox/1.5.0.6

Every time I go to http://perldoc.com -- firefox freezes completely.
I've left it for several hours with no change.
I also get the problem at http://wwwcn.cern.ch

I guess these domains have a bad DNS setup, but why doesn't firefox error?

Reading the headers with GET I see:
http://perldoc.com --> 503 Service Unavailable



Reproducible: Always

Steps to Reproduce:
1. Go to perldoc.com or wwwcn.cern.ch

Actual Results:  
Firefox just froze. No reponse. 

Expected Results:  
Displayed an error

Works for me. With both sites:
- http://perldoc.com
- http://wwwcn.cern.ch
firefox reports the 'Server not found' error page.

Does this happen to you in firefox's safmode?

Yes, it happens in safe mode as well.

I've tried this again in normal mode, and am now happily getting an error: "The requested URL could not be retrieved" after 5-10 minutes.

Will, do you still see this?

works for me with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b3) Gecko/20090305 Firefox/3.1b3

@Reporter, we have not heard back from you in a while, so I am closing this bug as INCOMPLETE. You can reopen this bug if more information becomes available. Some helpful information you can provide us is found at http://quality.mozilla.org/bug-writing-guidelines. You should also use a recent version of Firefox, from http://www.getfirefox.com.
