what if you were brand new on home and seen this mess up...?
If I were new to Home, I would have thought, "Wow! This brand new shirt looks really cool!"
People not being able to celebrate together wasn't SCEA's fault. It was the fault of the person who set the clock of their PS3.
Quality Assurance tests are done on a seperate closed server. Once the product passes the test, it is released on the public servers. The problem with public servers is the internet, internet traffic and each user's individual internet set up.
In my job for the Navy, I work for Quality Assurance. When a product leaves my hands it is in the best quality possible. After that, quality begins to deteriorate due to multiple people handling it and how it is stored and used. It is the same for our virtual items and updates. Once they leave the QA server, the product begins to be pulled apart (figuratively) by the sources I mentioned above.
