SSL 2.0: The Zombie Protocol That Just Won’t Die
SSL 2.0 turns 30, but over 422,000 servers still party like it’s 1995! Despite its deprecation, this outdated protocol continues to linger online, proving that some tech relics just refuse to retire. Let’s hope these servers finally get the retirement memo and stop crashing the modern security party.

Hot Take:
SSL 2.0 is like that one friend who’s still rocking the mullet—outdated, insecure, and somehow still showing up at parties it wasn’t invited to! Despite being officially deprecated over a decade ago, SSL 2.0 is still hanging around like a bad haircut, with over 423,000 public IP addresses supporting it. Time to call the protocol barber and give the internet a much-needed trim!
