I suspect this change: 18 February 2010: No more blacklisting of unresponsive servers, a 2 minute timeout is backed off to. And I saw that the requestlist he included is full of unresponsive servers. This fits with the graphs he sent, that see no increase in CPU (it does not do anything but waiting) with extra entries (thus those entries are on a long timeout). Looks like a tradeoff between how much work to put into trying to resolve to bad servers (: 16 lost packets, huge timeout). Otherwise the server used to be blacklisted for 15 minutes (infra-ttl).
