Yeah, I'm getting a bunch of alerts for Texas too. Seems like it might affect multiple areas and multiple carriers, but I don't really have a sense of exactly what's going on yet. I am seeing a lot of Cogent, but I'm seeing alerts for other carriers too. Curious if anyone else has anything. On Tue, Nov 25, 2025 at 6:49 PM June Slater via NANOG <nanog@lists.nanog.org> wrote:
