Google Audio Ads Sign-Up Page Live

Google Audio Ads now appears to be opening to sign-ups, sort of. sent me a heads-up about three new URLS that are (somewhat) active:

I can't get the overview page to load, at the moment. The sign-up page takes you to a page that says "Create a Google Account - Audio Ads" at the top. These seems designed for those who don't already have some type of account with Google.

Since I do have a Google Account, I followed the sign-in link rather than try to create a new account. This sent me back to the Google Audio Ads home page, which -- of course -- wasn't loading.

However, if I went to my main Google Accounts page, then in the My Services section, I could see Audio Ads having been added. Clicking on that link took me -- yes, back to the non-functional Google Audio Ads home page.

Others might have more luck -- perhaps this is just rolling out. Information for advertisers already leaked out earlier today. Or possibly, someone's stumbled onto the sign-up that's only open (and working) for preapproved account holders.
