Hi all,

We have two staff WFH on Starlink.

Azure MFA push notifications are intermittently not working since earlier in the week, and have completed failed since this morning.

If we check the Microsoft authenticator logs, yesterday we were reported as logging in from Canterbury, and from 8:50 this morning Microsoft identifies our public IP as Boise, Idaho.

Upshot is staff can't log into systems with Microsoft Azure push notifications.

Anyone else with similar issues?

Startlink are doing some changes.. seems they have changed their IP ranges so geoblocked unless the new ranges are added by the provider.

Check out my LPFM Radio Station at www.thecheese.co.nz - Now on iHeart Radio, TuneIn and Radio Garden

It's more of a problem with IP geo-location databases than anything to do with CGNAT

SpaceX publishes a CSV map of their address ranges <=> physical locations here, maybe double-check the addresses being assigned to those staff because they may not be listed yet: https://geoip.starlinkisp.net/feed.csv

Have seen others on /r/starlink complaining of the same issue which seems to be caused by SpaceX bringing on new public address ranges quickly before they've had the chance to add geo-location entries for them

Starlink IP address ranges are a total CF at the moment

The startlink NZ forum on facebook is full of these complaints
