Will continuously ping a heroku to see if we get any long delays

client.rb

#!/usr/bin/env ruby
$VERBOSE = true

require 'net/http'
require 'benchmark'

loop do
  delay = Benchmark.realtime do
    message = Net::HTTP.get('delay.heroku.com', '/') rescue nil
    puts "Instead of ping got: #{message}" unless message == "ping\n"
  end
  puts "Waited for #{delay} at #{Time.now.to_s}" if delay > 10
end

config.ru

run(lambda do |env|
  [200, {'Content-Type'=>'text/plain'}, StringIO.new("ping\n")]
end)
