[AusNOG] Dark Fibre going Error Disable

[Matt Perkins]

I will bet you a bottle of coke  at the next Ausnog that if you check 
with your dark provider they were working on a joint along your run at 
the time of the outage. We get these from time to time. link-flap 
usually allays is a result of work at the joints.  When they squash the 
head end back into the pit after the work the max bend radius can be 
exceeded. When that happens there there's refraction and loss.  We have 
one customer where the joint out the front of his building was worked on 
every 2 weeks and we got that result.   In the end we had to move carrier.

It happens the question is will your carrier be honest about it.

Matt.
