SoCal T-Mobile IPv4 sites inaccessible

I posted this on the outages mailing-list too, and I am hoping to get more eyeballs on this while also checking in to see if this is isolated to just us. On T-Mobile, we do not seem to be able to get to ipv4 sites. does not load, does. Even does not seem to be working.
I Tried this with LTE (phone) and their home-internet service.

Anyone else seeing this?

Thanks in advance.
