T-Mobile Traffic Changes
by David Farmer Aug. 1, 2025

Aug. 1, 2025

Last Night, around midnight, our traffic going to T-Mobile stopped going through MiCE. [image: image.png] [image: image.png] [image: image.png] It looks like they migrated traffic to their new MICE port. But we are no longer receiving any IPv4 routes from T-Mobile via MICE, but are receiving 5 IPv6 routes. We have also had instability (packet loss) with our IPv6 traffic from them for several weeks. Anyone else seeing this? Do you have any good contacts to get it resolved? Unfortunately, our contact with their NOC has not been returned or acknowledged.

IRR import and router update processes
by Miles McCredie June 4, 2025

June 4, 2025

Are the IRR import and router update processes running as expected? Asking because I'm seeing some announcements being IRRd filtered that I don't expect. Also, could you confirm which sources are being used? There are also some announcements with valid objects in NTTCOM that are being filtered.
