After the April 17th update,
I found my GW.exe send little amount of data to these IPs when starting the updating screen, the port is 80.
Not send to these IPs at the same time, every time I run Guild Wars it chooses one of these.
210.254.104.4 and 210.254.104.42
211.15.42.172
202.47.29.157 and 202.47.29.158
I've never seen these IPs before...or just I've not noticed yet.
And I checked them on Whois, showed these IPs are in Australlia.
Personally I live in Taiwan, and our data storage in American servers.
I donno that Anet host servers in Australlia.
And these IP seems suspicious, too.

Servers should be likely...not various.
I sent a mail to the community of Anet and haven't get their reply.
Could please any Anet staff confirm that these IPs are used by Guild Wars?
Otherwise my computer might be infected by spyware or something malicious...

Thanks very much in advanced.
