They have shifted 90% of their traffic off IXs and onto our full route DIA, anyone else seeing this issue or have insight as to what is going on over there?  We have been asking for help on resolution for weeks and all we get is we are working on it and now we get no response.  We were even sent an LOA and when the DC went to go put in the x-connect their patch panel was full.  How do they not know if they have ports open or not?  I have even reached out to an engineer who is on this list and he does not even respond.  

The last two nights the traffic levels to them has skyrocketed as well.  

Any insight?
