Using squid-6.0.0-20220905-r9358e99f9: ====================================== On sunday, one of our DNS server froze and was not answering any queries. Shit happens, that's why we have another DNS server. Our Squid config says: dns_nameservers 141.42.5.157 141.42.5.156 So, 141.42.5.157 was not answering any queries, and 141.42.5.156 took over. But... monitoring reported dns_query_time rose to about 8000ms, meaning all http requests took ages, since (I guess) the first dns server was queried, and (after 8s?) the second server was used. But according to the docs, "dns_timeout" defaults to 30s. Is there any way of making squid mark the first server as "dead" (for e.g. 5 minutes) and use the next server instead? -- Ralf Hildebrandt Charité - Universitätsmedizin Berlin Geschäftsbereich IT | Abteilung Netzwerk Campus Benjamin Franklin (CBF) Haus I | 1.
