Hi, I’m a systems and network admin, who loves to speak of and peek into infrastructure designs, and I was wondering if I could get any info on Mondo’s infrastructure for handling card payments, and the reliability thereof.
According to news sources the incident with people not being able to use their cards on that bank was linked to the outage on AWS services.
So I wonder, from the banking experts here at Mondo, how does it work, when an ATM, card machine or whatnot queries for a transaction approval, how does that happen? (Protocol-wise)
And, can an outage like this happen with Mondo as well, provided an underlying service outage in a single, region happens? (If Mondo uses AWS in the first place. I thought I read somewhere they do.)
