According to the DNS, the domain points to heroku:

Terminal window
→ host tumble.dasmith.co.uk
tumble.dasmith.co.uk is an alias for proxy.heroku.com.
proxy.heroku.com has address 50.16.215.196
proxy.heroku.com has address 75.101.145.87
proxy.heroku.com has address 75.101.163.44
proxy.heroku.com has address 174.129.212.2

Yet if I send a TRACE request, I get this back:
