Not necessarily. Some sites or providers drop all ICMP traffic to avoid DoS attacks. That would explain the failed ping and tracert sessions. Browsing by IP with HTTP/1.1 can have issues if host headers are in play. I'd say that it still is inconclusive one way or the other.

Telneting to port 80 on the IP address should answer as that happens before the "GET" command is issued and so host headers wouldn't get in the way at that point.
