This, most likely, is something that it completely out of Linode's control (and out of The Planet's control as well). There's a lot of internet between Bejing and Dallas.

I just ran a ping from Minneapolis, MN to my linode in Dallas - the ping ran for about 15 minutes and I dropped one ping during that time.

Some sort of pathping or traceroute or mtr might be useful.

All that content filtering, great firewalling, and deep packet inspection doesn't come without a few packets being sacrificed.

Yes. File a support ticket. You will get new IP addresses, however.

Fremont is the closest data center to China, but availability there is limited. Dallas is second-closest.

Fremont may not be much better for you -- try ping and mtr against fremont1.linode.com to see if it's an improvement.

This is true, but at least a little bit of space opens up occasionally. File a ticket and you'll be early in the line to get it.

Geographically, as the bird flies? Looks like you're right. Internet-wise may be different, though. Still, I guess it's worth checking London out just to see, but I'd be surprised if it was significantly better.

QFT. This is probably your problem.

Looks like your best bet is Fremont... It's strange, that the latency to China is so bad. It's about the same distance away as Australia, but I ping over 100ms less to Australia...
