**wdqs**: probably historically the first exposed service, provides SPARQL endpoint without encryption inside of the datacenter (encryption is terminated at Varnish), queries timeout after 1 minute **wdqs-ssl**: same as above, but providing SSL between the caches and the backend **wdqs-heavy-queries**: provides a SPARQL endpoint with a 5 minutes timeout instead of 1 minute, used by a few internal use cases (as I remember, those are some analytics workloads) The `wdqs` endpoint should be removed (only after validating that no clients are using it) and wdqs-ssl should be used instead. I suspect that wdqs-heavy-queries is still needed, but we might need to track down whoever is using it and check. Note that there is also `wdqs-internal`, which is used only for internal use cases that are known to not be expensive. This ensures that this cluster is a lot more stable than the others (and that's why -heavy-queries is routed to the external cluster, even if that traffic is internal. Confusing, I know). `wdqs-internal` seems to still be without SSL, which we ideally should change at some point. This isn't a big deal, as there should be no PII going to that endpoint.
