Are All Windows XP Updates Still Available in 2016?

I have not yet used WSUS OU 9.2.1 to download all the updates for Windows XP yet, and I read in the thread linked below that Microsoft has started to remove Windows XP updates from their servers. Is this true? And if it is, are these updates still available elsewhere and if so, how would I go about telling WSUS to download them?
Here is the thread to which I was referring to:
