The keyserver pools operate as such DNS Round Robins. I wouldn't generally recommend it for individual nameservers. (i) If the servers are in physical proximity (same DC), you're better off with, in the case of nginx, usptream: https://blog.sumptuouscapital.com/2013/10/load-balancing-sks/ (ii) if the servers are in different datacenters; use separate hostnames to access the servers, using DNS RR for this will confuse monitoring of the server (e.g otherwise both servers will drop if crawler hits the down server, even if the other is operational, as there is no retry, as opposed to what you get from upstream module), it also would impact measuring for geographical pools etc.. so depending on level of weirdness, could result in exclusion from the pool. -- ---------------------------- Kristian Fiskerstrand Blog: https://blog.sumptuouscapital.com Twitter: @krifisk ---------------------------- Public OpenPGP keyblock at hkp://pool.sks-keyservers.net fpr:94CB AFDD 3034 5109 5618 35AA 0B7F 8B60 E3ED FAE3 ---------------------------- Aquila non capit muscas The eagle does not hunt flies
