The response I had yesterday when one of mine was still down after they claimed the original issue as resolved was:
The Australian Data Center issue is specific to the sites which are using External DNS and they are pointing to the IP 22.214.171.124
If the Ip is changed to 126.96.36.199 instead of 188.8.131.52, it should resolve the issue.
I found this did work to get that site back up, as it was indeed using external DNS. Not sure if this will work for you.
During this period, one of my other sites mysteriously had its primary style.css file truncated to zero bytes - an error during internal migration I would assume.
I was just informed by the customer support team that they are currently under a DDOS attack
"What is happening with the AU DC?

Please accept our apology for the inconvenience. We are under large DDOS attack and working against it. This is our top priority and only priority at the moment. Unfortunately, we don't have an ETA at the moment."
