F14 no http access to certain sites (only on F14)

[daytooner]

I've been running several machines on F14 for quite awhile, and everything was working hunky-dory. All of a sudden, though, http access to certain sites stopped working.

Most sites DO work. Some sites that don't: www.facebook.com, www.mozilla.org.

This is what I get when I run wget:

[ken@Bugs ~]$ wget www.facebook.com
--2012-05-07 10:49:45-- http://www.facebook.com/
Resolving www.facebook.com... 69.171.234.21
Connecting to www.facebook.com|69.171.234.21|:80... connected.
HTTP request sent, awaiting response... Read error (Connection reset by peer) in headers.
Retrying.

--2012-05-07 10:51:48-- (try: 2) http://www.facebook.com/
Connecting to www.facebook.com|69.171.234.21|:80... connected.
HTTP request sent, awaiting response... Read error (Connection reset by peer) in headers.
Retrying.

Note the LONG pause after the HTTP request sent and the Read error.

I have a windows XP machine on the same network, and it can access these sites. So it can't be the firewall or router, or any other switches. And since it occurs on only those machines - the ones with F14 - I can only narrow it down to that.

This did work until about a month ago.

Kind of desperate here. Can't upgrade to F15+, since these are older machines with only 512MB (is there a way around that?). Any help greatly appreciated.

TIA

You tried to wget Facebook's whole site?
What exactly did you mean to do?

This part "(Connection reset by peer)" says they disconnected you, I'm not surprised.
