My wife's is in SOS mode here in Michigan. She can't even make calls over Wifi with the wifi calling feature enabled.

I'm on AT&T which is fortunately up and working - but it sucks so bad at a baseline level that it might as well be having an outage too lol.

1. How many people have a VoIP solution on their phones to use over WiFi in a case like this?

2. What is the percentage of homes with twisted pair landlines down to these days?

afaik most carriers in the US offer a form of voip over wifi. it needs to be enabled for your phone.

This is called "Wi-Fi Calling" and it also seems to be down for those affected. (n =~ 150 phones I'm tracking)

On my phone in Seattle Verizon Wi-Fi calling doesn't work but FaceTime audio does.

Yep.

Wi-Fi Calling is a mix of GRE/IPSec tunnels to carrier servers (which were still functioning during the outage) that then hook into cellular infra on the backend (which wasn't working). On my firewall, I was seeing phones make that GRE tunnel connection, but it was just a gaping void after that.

FaceTime does not use cellular infra at all (except as a potential IP network interface)

We also had issues in Michigan with Verizon, but they seem to be corrected now.

Im from Michigan and its not corrected in Michigan yet.

With most 2fa systems going through people's cell phones, this is scary.

2FA via SMS is 1.3FA at best: an inherently insecure medium on a network that can go down. What's more annoying is that most web services won't allow the use of VoIP numbers for 2FA.

I'm in SOS mode in Tennessee.

I am back online as of 2PM PDT in or.us.

SOS mode in Utah also.

Still down in AZ.
