There was a power blip, and a report that the system was no longer on battery at 11:08am BST.
10 minutes later we started to lose connection to the sensors at the site.
It could be a a total loss of UPS, As it was a sudden loss of communication, but could also be external to the building at the telco exchange.
Is the backup line working? Should there not be sprint and Verizon connections?
Loss of both circuits points at power / hardware internally or external to the MDF.
Only facilities would be able to check.
