Since this is the unofficial Minnesota outages list...

We (Wiktel) cannot reach certain things (e.g. Verizon cell phones)
through the Lumen access tandem in Grand Forks. Another nearby LEC has
confirmed the same.

We also have an SS7 DS1 down to Inteliquent (as formerly INS).

Lumen is "already working tickets related to multiple DS1’s, DS3 down in
North Dakota".
