Hi, I disabled the sibling on both squid servers, we got one 504: TCP_MISS/504 361 GET http://rate.msfsob.com/review?h=www.searchhomeremedy.com - HIER_DIRECT/8.25.35.129 A wget on this url gives a 404, so here we can say the object does not exist, the TCP_MISS/504 seems a correct answer. But no new 504... the ISP is a 500Mbps. If we enable the sibling, we get one/two 504 every second on both squid. any idea ?
