I think this was at the actual processor, not the traffic in getting there. I tried to go to their web portal and that was all kinds of messed up too.
I guess a big outfit could afford to have a couple different processors to go along with a couple different communication systems. We had a little PayPal Here unit (similar to Square) that no longer works. They sunsetted it. Didn't work for any PIN transactions anyway so really wasn't that helpful.
