Slow web page => 503 error

[Philip Rhoades P]

People,

This page is slow to load in Chrome but it does eventually display - but I keep getting 503 errors with this script:

#!/usr/bin/ruby

                                                         

require 'rubygems'

require 'nokogiri'

require 'open-uri'

node = Nokogiri::HTML(open('https://localbitcoins.com')).css(table tbody tr td)

node.each {|child| puts child.text}

Any solutions? - a lot of Googling didn't help . .

Thanks,

Phil.
