Fair enough... I can see the same thing from here as well but not having any issues reaching the site - is this kind of "outage" acceptable to this list? Perhaps I am misunderstanding the purpose of this list (I'm thinking major site outages, major network outages etc)? paul@netops:~$ ping www.tcpdump.org PING www.tcpdump.org (132.213.238.6) 56(84) bytes of data.

I can pull up the site no problem today and was able to yesterday as well - and my DNS was resolving to 132.213.238.6
The original poster simply asked "anyone seen this before?" - there was no indication of WHAT the problem was and how it's operationally impacting (therefore appropriate for this list as I would understand it).
Just because you are seeing "host unreachable" doesn't mean that the content *behind* it won't be served. Someone is doing some filtering on their router/firewall - pretty common stuff.
Am I missing something here? ;)
--As for the rest, it is mine. Just that a 50% loss rate and a *4 second* ping time aren't considered 'normal' for most networks. ;) (And are usually a sign of something seriously wrong someplace...) Oh: and 'host unreachable' isn't the same as 'filtered from the host': It means the previous hop doesn't know how to send the packet on. (Traceroute would normally show a filtered/lost ping as a splat. H! means it got back a reply saying that the host was unreachable.)
