For example: http://terokarvinen.com/2016/prefer-ipv4-on-ubuntu-16-04-lts-xenial-etcgai-conf-precedence-ffff0096-100 (summary is to prefer ipv4 to ipv6, rather than the other way around: uncomment line "precedence ::ffff:0:0/96  100" in /etc/gai.conf, if applicable to your system). I've done that on the community servers and haven't seen any issues btw.
