I'm not entirely sure what's causing your issues (as Richard said, raise a ticket) but there are a few things which stand out.
1) Your DNS is using the Heroku IPs - something which is now actively discouraged. https://devcenter.heroku.com/articles/custom-domains#dns_setup (I also wrote about this a while back: http://neilmiddleton.com/the-dangers-of-a-records-and-heroku/) 2) You appear to be serving static assets from your dynos. I'm not sure what stack you're on, so you might be using Varnish, but as your requests are hitting your dynos I'd guess you're on Cedar. If so, you really need to think about getting those assets off of your dynos and onto something like S3 / CloudFront. Anything you can do to alleviate the HTTP requests onto they dynos is going to help.
