Hi folks, I'm looking for a DISA/DOD contact who feels that my issue has merit. I've tried the DISA Helpdesk and have been told since I'm a commercial entity with no affiliation with the DOD, they can't help me.
The issue at hand is that our /23 netblock has lost communication (at least email TCP 25) with AS345 / AS721 as of May 31, 2024 and I cannot figure out why. We are in a Flexential datacenter in Richmond VA and use Flexential for transport. We cannot send emails to .MIL or receive emails from .MIL. It is not that they are being rejected on either end. The deliveries are timing out and being returned to sender, from both sides. I don't know if DISA/DOD has a block on our ASN and-or /23, or if there is a routing issue somewhere between us and AS345 / AS721. I had asked the Flexential folks to look into it from their side, and they indicated that historic data does indeed show that there TCP 25 communications to and fro between us and AS345 prior to June 1, but nothing from June 1 onward. And all they could say was that they (Flex) were not in any way blocking. And I'd agree with that. As you can imagine, my customers are not happy with not being able to communicate with their family / friends via email in the MIL domains, and our customers who are vendors / contractors cannot do business with the military effectively if they cannot send/receive emails. us --> Flexential --> GTT --> Level3 --> Qwest --> ? --> AS345 / AS721 Any idea where one would go next? Is it likely that any of those entities further upstream like GTT / Level3 / Qwest would even assist since we are not their customer? Thanks for your time! Mike Tindor
