You're missing the last trace
Should be something like:
16 168 ms 169 ms 171 ms 52.60.1343.static.theplanet.com [67.19.96.82]

MTU
- Very good point from Master Kevin
- The MTU can be an Issue:
Test your MTU from the problem server by pinging the gateway of your router:
ping -f <router gateway IP> -l 1472
You will get one of three responses;
the ping will return, "Packet needs to be fragmented but DF set." or it will timeout.
If the ping timeout, that means a downstream router has a mismatched MTU,
and is the probable reason for your connectivity issue. Incrementally reduce
the 1472 until the ping returns.
If you get the packet needs to be fragmented but DF set, at a low number of
less than 1400, see if you can increase the MTU without a timeout. Ideally
you would really like a number as close to 1500 as you can get.Carefull MTU
to a much too low of a number and it would affect your network performance.
Check the MTU max size on your router.
Also check:
Installing security update MS05-019 or Windows Server 2003 Service Pack 1
may cause network connectivity between clients and servers to fail

Also check any filters on switching devices or routers, etc...

I can't reach the site with the command ping, and I get this with a
tracert:
I'm not sure what to think about the tracert, this site is pingable. Were
you able to do a straight ping to the site or was it ping with 1472 byte
packets the one that didn't return. Did it timeout or did you get packet
needs to be fragmented but DF set?
If it timed out reduce the 1472 until it is returned, that would be you MTU,
find the problem interface between you and the site, or reduce the MTU on
the interface on your machine to that number plus 28. Then try to access the
site.
