AWS is sending info

Since installing the “Live” version my firewall stops an ip address a dozen or more times per day. The specific ip is: 64.124.109.237 I tracked it down and discovered it was AWS, owner of WeatherBug. My live version appears to work ok, aside from known bugs in the beta. So, can/should I unblock this ip? I used to use WeatherBug but stopped because their ads were annoying.
Thanks!

baronjames, WeatherBug supplies the weather data for Weather Watcher Live, so you’ll need to leave that access open.

Thanks Mike, I figured it would be ok, but everything seemed to be working without allowing access to that ip.
