I was looking up on imageserviceparameters and i stumbled upon this website that looks like and old version of ESRI's. Some links are broken some work. (the URL is different)
imageserviceparameters-amd | API Reference | ArcGIS API for JavaScript
and the real website
imageserviceparameters-amd | API Reference | ArcGIS API for JavaScript
Yes and no.
I recognize that domain and know that the developer associated with that site is a regular here on the forum. My guess is that they are hosting the JS API (and obviously the SDK) locally on their server and, for some reason, that content got indexed by Google.
Unlike Dojo, ESRI's hosted documentation only applies to the current API version. If you want to preserve the documentation for a previous version of the API, you can download it. Again, that seems to be what has happened here.
I have searched in GeoNet for that name and I have found some people using that url for their applications. I don't know how reliable that is and why create another instance if everything is working right from previous versions. Just to use up your host space?:-??
