The issue is now fixed, site is online again.
I'm sorry for the delays guys!
We have a problem we are fixing. We cannot possibly answer all incoming notifications regarding the issue though.
Please sit tight. Can't give an estimate for a fix, but once it's up I'll update our Twitter feed, and this thread. Also we'll remove the notice on the SS site itself once the services are running again.
Edit: this issue is the cause to all the "Publisher ID is invalid" errors lately, in case you have encountered one.
- the issue also affects all other actions requiring Publisher IDs, like verifying accounts.
- We do not have an estimate yet. My assumption is that the nature of the error is such that once it is found it can be fixed immediately; so the first schedule we can report to you would be along the lines "now it has been fixed". That said, I'll update here whenever I have anything new to disclose.
