Following an investigation with the datacenter manager on-site, we have concluded this to be a bad patch panel box that contains all of our fiber connections from carriers.
In light of this finding, the datacenter has replaced the patch panel box and all optics connected to our core devices. We hope this will resolve any outages we have experienced today. We will continue to monitor over the next 24 hours. If this does recur, the datacenter has reassured us that there will be technical staff on-site who will be able to take actions to bring connections back up.
