Funny enough, I'm on the other side of the world and was getting 30-40% packet loss yesterday. Something's wrong with the internet... must be that new worm or something.

Kavai, your log indicates pretty bad loss at a LEVEL3 host, which is unfortunately one of those machines after your ISP but before ours. There's not much you or we can do when that happens.

Lee, is there a way for me to contact Level 3?


I'm no network analyst so can you tell me which server is droping all the packets?

Their website appears to be: http://www.level3.com/

In your table, ae-1-52.bbr2.LosAngeles1.Level3.net is the only one that lost data (7% loss with 976 sent and 911 received).

7% isn't that big a loss. I really don't see the Level3 device as the problem based on that snapshot.
