There is no traffic through squid box at that time, and I can use fetch or wget tools download that web page completely just on the same machine at the same time, and all squid boxes with various config I have tested can not fetch that page any time in the day. So I don't think this is a firewall or overload issue, it must be the communication problem with squid and the server site. I'll be very appreciate if you can tell me the detail of this problem and how I can get through of it. There are many sites using this frontend accelerator cluster, en.beijing2008.com just one of them(you can see it from the DNS resolve result, chinacache hosts all of them). Thanks.
