We are with US Cellular on our phones. With local (TDS) Cable Co for puter, but our phones are intertwined with the puter etc.

im on ATT's UVERSE.@Clb... I see you are also coming from California...
Are you using T-Mobile / Verizon ISP?
Being it appears it's just us two noting this, and it's the same site ( which looks flakey to me ), I get the idea we two just got caught up in a network DNS glitch.
IDIoit posted above a missing piece which, for a while, recreated the exact page I was seeing. For some reason I do not yet understand, my system has resumed inserting the www into the URL whether I put it there or not. On both phones. On all three browsers: Brave, Chrome, DuckDuckGo.
I don't seem to have much say in my DNS server... It seems private to my ISP, which is T-Mobile / Verizon.
I may never know what just happened, but I leave my experience here in case others had the same mystery. Sometimes finding someone else's report can sure put ones mind at ease to know if someone else saw it too, as Clb did for me. Otherwise I would still be on high alert that some script is sending me through a proxy server .
