Re: WHAT IS CAUSING THE DISCONNECTS?
Alex, using cogent, do you see these issues?
fra03 is the IXS Interxion in Frankfurt, which is where some others have mentioned issues. From my checking with my tracert at home, I actually don't use the cogent routers in fra03, but others mentioned it as an issue.
Global crossing uses fra04, which is Interxion also, just in another building, which they most likely have inter IXS routing between IXS's, so really they are all traveling through the same links to get to INXS in Munich, then to SIX-SK in Bratislava then to BIX.
Here's the info of the most likely path for cogent, I can be sure about gblx because the routers don't reply to icmp.
