Update – Troubleshooting transport link failure

8:56PM – I’m still on hold with the transport fiber provider’s support department while they investigate.  While on-hold I have manually moved the majority of subscriber traffic to a backup link for a partial service restoration.  Unfortunately, this backup link has about 5% the required capacity to carry the evening traffic load.  I’m working on ordering a temporary capacity increase on this circuit for the duration of this outage.
Most subscribers should have service restored, though speeds will be quite low for now.
More updates to follow.
