"Site Not Available" PSN error?

Trying to access PSN (http://store.playstation.com) from any PC gets me this error (before even prompting me to login):

[EDIT] I even get this error using the Android app:

What I find strange is this a PSN error. Not a browser error, but something PSN is saying.

Or trying to login to PSN on PS3/PS4/phone also gets a generic error. What’s wrong, what does this error indicate? How can this be fixed?

I’ve tried rebooting, I’ve tried Chrome in incognito mode, I’ve tried different computers etc. All get the error. This has been like this for 24+ hours for me now.

I’m in Albany NY

[EDIT] Sony support was no help. They replied;

xxxxxxx: Unfortunately this error does not belong to us http://i.imgur.com/c10TvjC.png, please try another browser or another internet connection.

What’s even more odd, is that I was able to update my PSTV during all this. But as soon as I tried logging onto PSN on the PSTV, I got a connection error. The internet is working fine though.
