With the problem obviously well before the Mozilla network I'm not sure there's much we can do about that since we don't control any of it or have a relationship with the ISPs.

As Peter said, the issue is at the ISP level and the "Chinese firewall", it has up and down and we can't do much about it. It's probably going to be back to "normal" soon-ish.

OK. I understand. Is there any way to have a server IP address that have less latency to China?

Adding a Needinfo on fox2mike as I don't know how is the CDN/servers situation for China.

There is none. No CDNs and we turned off Zeus as well.
