Okay, so for what it is worth, I fired up my PS3 (this wasn't much work, to be clear, I keep it hooked up to play my physical collection), and loaded up the store. It works fine for me.
The store took a little longer to load than I was expecting, to the point that I was waiting on an error message, but then it was fine and I'm currently on the Silent Hill purchase page.
So this rules out the possibility that the store quietly got shut down. It was my understanding that Sony was originally going to do that in the summer, but got blowback and opted to keep it running for the time being. I wouldn't put it past them to then quietly disable it, but it's working fine for me.
There was also no update, and I believe the last time I updated was at the start of September. That was likely the one that Phil says 'bricked his online portion'.
This is definitely a Phil problem. It's just the question of if you believe it is with his hardware, or his head.
