How do we know when BT lines are 'down'

[Unitrust]

We were told that the BT lines were down yesterday  (15th April) by our service provider and have been told this several times by our IT support people.

Is there a way to verify this?

Help appreciated, thank you.

Hi. There should be a notification email sent to the admin too. Not sure but you can also check the customer portal.
