If the red zone starts to fade before you've made it out, you're going to get hit. It's not even latency, that zone is designed specifically to show YOU the window you have to get out, and where you need to move to do so. That window is shut the moment it starts to fade.

Otherwise, it's a latency issue, and not one that I can say I share. I've never walked out of a target zone before it started to fade and still get hit.
