Hi Christian,

No problem. I saw your shift log entry.
We have already done the needed tests on FST before the shift started, so we 
are just waiting for the cooling to be ready.
FST is not crucial for the current cosmic data taking, so we are not very 
urgent. Of course sooner is better.

I tested this morning but I can not ping the device.
So, I guess we will need to wait it being whitelisted by Wayne or Mike as you 
mentioned earlier.

Cheers,
Te-Chuan
