  A few notes in reply to the comment above:
  
  - This ticket is specifically for 3 experimental endpoints that are temporary 
and will be used to gather feedback from our communities. We expect low amount 
of traffic, so this reduces the risk. We should still think about the long term 
solution if it needs to be different than what we currently have for WDQS / 
WCQS, but that can be done later.
  - We have fairly low TTL on the SPARQL requests (5 minutes). Not having 
caching at all is probably not a big deal (but we need to check the numbers - 
we might have a few hot spots that the cache helps). For the experimental 
phase, not having cache is very unlikely to be an issue. The UI is a bunch of 
static HTML / CSS / JS files that have a longer TTL, but they are also super 
cheap to serve.
  - In the long term, loosing requestctl seems to be a big deal. WDQS is one of 
the services where requestctl is regularly useful.
  - Increased latency due to SSL termination is not an issue. SPARQL queries 
tend to be at least an order of magnitude longer, so user impact is negligible.
  
  Additional notes:
  
  - Timeline: we'd like to have experimental servers publicly accessible in 
mid-January
  - short term solution for experimental servers and long term solution for 
WDQS as a whole should probably be treated separately
