<p>AppHarbor load balancers only respond to traffic on TCP ports 80 and 443 (for HTTP and HTTPS respectively), so ICMP pings will always timeout. Any particular reason you want to ping them?</p>

<p>Ok got it -- I think in any case testing website availability isn't the best solution as it can easily result in false negatives (as you've experienced since a ping will never succeed), but also false positives in the event that the load balancer responds successfully to a ping request but the website is still down. Instead I'd recommend using curl or similar to make requests to your website, or alternatively set up a website tracker such as Pingdom to test your website.</p>
