server down?

i have been trying to S-off a few HTC 10s, earlier this morning i got it to work on one but when getting to the second one the process stops at:

Connecting to the server…
Please wait, processing your request…

the Do S-Off button then remains greyed out, so i tried installing the software on another PC, pressed the activate software button and it just sits at "connecting to the server" again with the button greyed out

so im guessing the servers are down, any ETA on when they will be back up?
