Shopping cart using Authorize.net is still down. It turns out that they made some changes and DXCart, the shopping cart company was unaware of it. And they, DXCart, say it will take a week for them to upgrade.
Paypal still works. And I will be looking for another company tomorrow.

On the technology plus side, I now have a phone again.  Took two hours  at Verizon.  “We have never seen anything like that,” failure.
