"Our Static IP reservation system is currently not responding"

Trying to activate my static IP using your TI Service Management Tool. The site gives me the following error message :

"Please note: Our Static IP reservation system is currently not responding. We cannot allocate your IPs now. We apologize for the inconvenience. Please try again later."

You technical department was unable to fix it and I've been trying for a while now.

How do I get passed this error?
