Very odd problem.. Today I felt access to a particular website was rather slow, so I decided to do a traceroute to the site in question to see if my ISP had a routing issue. However all I get is * * * on every hop including the 1st one. It doesn't get anywhere at all. Just time out, time out, time out. So I tried ping.. ping works fine. It resolves the DNS, and the ping is returned with no problems. I can load plenty of websites, including this one. So I fired up my windows box that is on the same network, same router.. traceroute works fine to the same sites. What is even more strange is I can traceroute over a VPN to my machine at work.. but traceroutes to sites that work on my windows box fail to work on my mac. Any suggestions? Thank you. Probably something simple but I can't work out what's causing it.
