It doesn't change the fact that very few things can be done to stop or even manage DDoS.
You can still try to look for how to find the persons doing it and DDoS them unstead but good luck with that.
And for those asking for compensation. SE would need to go case by case since it's different with every one. So it's impossible. The easier I though about was an option to freeze your sub so that you don't lose sub day during the time you can't play. It may be unfair since some can play but, what else can be done really? Nothing, it would have been done by then otherwise. Blaming SE is nice and all but won't change how it is. I don't think they're more happy than those complaining and the others about the situation.
