Apple SMS/Voice 2FA Down

I can't get get into my developer account because SMS/Voice 2FA seems to be down. The error is "Verification codes can’t be sent to this phone number at this time. Please try again later."

Server responds with 500 with the following error information:

  "serviceErrors" : [ {
    "code" : "-28248",
    "title" : "Verification Failed",
    "message" : "Verification codes can’t be sent to this phone number at this time. Please try again later.",
    "suppressDismissal" : false
  } ]

Same problem signing into the same account on macOS, both SMS and Voice verification give the error.

Of course both the Apple System Status (https://www.apple.com/support/systemstatus/) and Apple Developer System Status (https://developer.apple.com/system-status/) are both showing all green.

I had a friend try with his account and phone number and got the same issue. Anyone else here experiencing this?
