Problems with eBay Plus sign-up page.

Is there a known bug/fault with the eBay Plus sign-up page?

Have been trying to re-join eBay Plus and receiving the same error screen ("It's not you. It's us.") every time for several hours now. Same result on multiple devices and also when another family family member tried to check it on their own separate account. Same result even after clearing cache and trying on alternate browsers (firefox and edge).
