Grateful if anyone from Lumen with some clue can reach out.
They appear to be dropping traffic to our name servers (ns3.seacomnet.com + ns4.seacomnet.com) at our interconnect transit edge with them in MRS. Naturally, this is causing whoever is on their network to fail DNS queries to zones hosted on those name servers, which is causing all kinds of breakage, e-mail included.
We can’t e-mail them because, obviously, they can’t verify our source domain names; and what should be our AM’s appear to be on some kind of holiday.
If someone from there can reach out to me (ideally from a non-Lumen/CenturyLink/Level(3) e-mail address), I’d be terribly obliged. Thanks.
