Is the MITM cert their logon page?
I've been annoyed at logon in Simon malls and use my cellWAP instead.

I have a habit of checking personal and work servers from various locations. If 
I remember correctly I only checked Google and my server. They didn't break 
HTTPS until I visited my personal server that uses Let's Encrypt. No browser 
warning until then. Viewed cert and they were trying to pass one from AT 
Disturbing.

Yeah, I have two things I do to work past this.

First, I change DNS servers to use OpenDNS immediately after obtaining
DHCP leases.

Second, all of my browser traffic is proxied. I mostly use SOCKS over
SSH to my server at home. Sometimes I use Tor.

Could it be part of a content filtering setup?  With https they can't 
watch the content itself unless this sort of a MITM configuration 
happens--requiring the user to accept what appears to be an invalid 
certificate.


In my personal experience both Ruckus and Cradlepoint have options built 
into their offerings to enable this sort of invasive behavior in the 
name of filtering the content--usually deployed where there is free WiFi 
to the general public and they want to attempt to minimize people 
looking at things are not appropriate for that venue.  It may only take 
over when visiting domains that aren't on their white-list which could 
explain why Google makes it through OK.


LinkNYC had all sorts of trouble last year when some members of the 
local homeless population were using the kiosks and free WiFi to view 
pornography and perform inappropriate acts in public.

The other day I'm at Red Robbing grabbing a burger and I log into the only open 
wifi accessible. I notice that when you go to a popular website like google all 
is fine. When you go to a lesser known website using https (in this case a 
personal server in Europe) it does a man in the middle using an invalid cert 
from AT I didn't have time to play with it more. Such interesting behavior.
