Unable to login to Workspaces (Failed component code: U:svr.Forbidden)

Anyone else come across this issue when trying to log in to workspaces.acrobat.com?

The friendly error dialog I receive after logging in:

"Acrobat.com could not contact the server to complete signing you in.

It's either a momentary glitch with our service or a problem with your connection to the Internet.

Click 'OK' to try again - if it was a momentary problem, it will work the second time. If we still can't make contact, make sure you have a working connection to the Internet."

Detailed Error Message: Failed component code: U:svr.Forbidden

Other acrobat.com services seem to be working well enough for me. Any help would be greatly appreciated.
