The !H indicates host unreachable. I'm guessing that some router near the host has a 4.5 second ARP timeout. It's not a latency issue, but probably an end host issue. On Fri, May 9, 2014 at 11:12 AM, Kyle Farmer <bannereddivpool@gmail.com>wrote:

Can anyone verify what is going on? I called them a few weeks ago so I'm hoping this might hit some admins who work there.
