Eircom connectivity issue
|
|
Hello.
I've ran into a puzzling scenario and I thought I'd ask around to see if
anyone else has an idea.
I have a customer who operates a server on our network who informed me
that a customer of his out of Ireland is having connectivity issues to
it. The ISP in question is Eircom, and the block that seems unreachable
is 86.40.0.0/13.
Any trace to an IP in that block drops off the Earth at the edge of the
Tier 1 provider that we connect with, such as AT&T and Sprint. I've
also tried Level3, but the traffic goes over to AT&T in the end anyhow.
I've checked Level3 and Sprint's looking glass and performs a traceroute
from there, and I get the same result, so it doesn't appear to be an
issue with our network.
I'm at a loss and my customer told me that his customer has already
contacted Eircom and they are at a loss to explain the disconnect as
well. Does anyone have some insight into this?
