Can't access certain sites

[gus]

I have two computers (one WinXP, one Mac) on a home LAN, with a router
and DSL
access thru SBC to the internet. Using Firefox or IE6, I can access
most internet sites
without a problem. However there are a few sites (www.craigslist.org)
which I cannot
access. For these sites I get a "site unaccessible" or a timeout. Also,
I can't get a
ping response or do tracert to these sites.

I can't imagine what would block access to sites selectively,
particularly since the
problem is the same on two completely different computers. Anyone got
ant ideas?
Is this a problem with my ISP?

I would check the MTU first. These two links may help,
troubleshooting ie issues Can't access some web sites Can't access some secure web pages ... That computer can access some web sites like www.chigaotech.net but not Google.com... ...

Cannot load pages from specific web sites Other websites load fine, although eventually some link to another page won't ... Troubleshooting ie issues Can't run IE Can't access some web sites Can't ...

This is probably related to your isp as it affects both totally different
machines , or it could be a problem with your router not being able resolve
the address? best idea would be to call your isp
