Strange Network

A couple of days ago I came across www.just-ping.com site (it's a simple ping test site).

I tested my site avensen.com (IP: 72.232.147.154) with it, and got bad results like this one:

Melbourne, Australia Packets lost (50%) 199.6 205.5 208.2
Singapore, Singapore Packets lost (70%) 257.4 260.3 262.5

I'm trying to figure out if this is a network problem or a problem with my server. I don't get it, because there are no lost ICMP packets when I ping another hosts from my server, or when I ping my server from home PC.

And here is what server4sale support wrote:

This is what we received from data center and will update you, when they get back to us.

"We apologize for the delay in responding to you. We are aware of an issue that involves our upstream provider, and we have opened a ticket with them to get the issue resolved ASAP. We have asked them to investigate this issue and attempt to isolate the cause. Once we have more information from them, we will update you here in this ticket.

In the meantime, if you note any changes (good or bad), please provide traceroutes BOTH "TO" your server, and "FROM" your server, as well as a 300 count ping summary. This request has been made by our upstream provider, as we will forward any additional pings and traceroutes we receive directly to them. Without the traceroutes both to and from the servers, the information will not be useful for their investigation.

We will provide you with updates thru this ticket as we receive information from our provider. If you have any additional questions, or need further assistance, feel free to contact us. We appreciate your patience, while we work with to resolve this issue."

Second message from support:

Quote:

The data center has informed that they have not yet received an update from their upstream provider as they used to inform them after performing changes.

However, for better investigation and providing the results more precisely to their upstream provider they have asked you to provide the latest:

Quote:

1) 300 ping results from your PC to server

2) Traceroute from your PC to Server and

3) Traceroute from Server to your PC

I'd really appreciate if you help me to get these results and isolate the problem.

IP of my server: 72.232.147.154

What's even stranger is that when I run a just-ping.com test over 72.232.147.174 IP (a machine in the same SAVVIS data center, I guess), I get "All OK results":
