Found this on stackoverflow for resolving the issue in Ruby:

It seems to be a problem with certain versions of libc which resolve DNS routes. After spending couple hours to search solution you just need to add require 'resolv-replace' at the beginning of your code.

More information: Use Ruby DNS resolver to handle DNS timeout in Net::HTTP - Pull Request #597#issuecomment-40507119 - ruby/ruby - GitHub

Hope this help somebody in the future.
