Update :

We have received over 15,000 visit requests per minute and confirmed that the servers are unable to keep up with the high server load.

Due to the number of requests which makes it difficult to resolve the issue while keeping the Data Center Travel system open, we will temporarily suspend the Data Center Travel system and gradually open this feature as we monitor the situation.

And yes, if you are on the other datacenter, you are stuck there, like me.
