I would'nt sign in to it for sure

But it stopped me from being able to do anything at all, other than 'browse' items

I could not sign in to my own account (I had no problem when I first got home this morning)

Could'nt view feedback and it was telling me my own account did not exist when I tried to sign in again, and then shortly after I tried again, it told me my details were not correct

Could not use eBay as 'eBay' at all without it diverting to the sandbox each and every time

Interesting thing was, it happened minutes before eBay posted their brag/blurb on here

Given how many things they manage to stuff up when they update/add something, I would be very surprised if it was'nt related
