This is... beyond stupid, I guess?
Sony, I'm really glad I stopped paying for PS+. This sh!t should NOT happen. Especially in a game that is focused on ONLINE gaming.
No, it's exactly how protection works.
When the "security measure" ended up actually taking the service down - yes, that is stupid.
No, it's really not. The game caused behavior patterns that were put in place because 99/100 times, those behavior patterns predict DDOS. Here, it wasn't, so they fixed it. It's not 'stupid', it's actually 'really good they have these protections in place'.
The same thing happens in all areas. For example, if certain behavior is nearly always fraudulent credit card theft, and you suddenly buy, say, 10 PS4s for your friends, your credit card company is likely to freeze your card, call you, and make sure your card wasn't stolen. It's not 'stupid' you triggered their protections, it's -smart- they had those protections in place.
The amount of people in here acting like this is lol-worthy, or stupid, or whatever is mindboggling. I mean, sure, it's a bit funny, but it's neither stupid nor something Sony should be ashamed of.
There was a game a couple years ago that had similar issues because it pinged servers like 100x more than it should. That was a bad design decision that got rectified. This, however, is just a case where legitimate use looked like an attack.
