Ever wonder why losing 4G sometimes also causes loss of 3G?

It's explained here:

IMS software bug caused Verizon LTE outage

I know it's not a brand new article, but I hadn't seen it before. If you have, my appologies.

At least now I understand.

One thing I still don't understand is this... why doesn't it pick up 1x when it can't get 3G/4G?

I mean, I still have 4 bars of voice - isn't that basically 1x? And has nothing to do with LTE/3G/4G? Maybe the radios just get so confused that they can't even do 1x? I dunno.... but it doesn't seem to me like there is any technical reason why you would have "no data" instead of "1x".
