Is the SHA256 value in the bitcoin address wiki accurate? From the wiki page https://en.bitcoin.it/wiki/Technical_background_of_version_1_Bitcoin_addresses the example of "How to Create Bitcoin Address" shows the SHA256 of:

0450863AD64A87AE8A2FE83C1AF1A8403CB53F53E486D8511DAD8A04887E5B23522CD470243453A299FA9E77237716103ABC11A1DF38855ED6F2EE187E9C582BA6 

to be

600FFE422B4E00731A59557A5CCA46CC183944191006324A447BDB2D98D4B408

If I use this online tool http://www.xorbin.com/tools/sha256-hash-calculator

I get: 32511e82d56dcea68eb774094e25bab0f8bdd9bc1eca1ceeda38c7a43aceddce

Am I missing something?
The problem is that you're treating the pubkey as string data. What you need to do is treat it as raw binary hexadecimal. If you use fileformat.info and calculate it using Binary Hash hex bytes you do indeed get 600FFE422B4E00731A59557A5CCA46CC183944191006324A447BDB2D98D4B408.
