Are death timers longer?

Hi, I haven't played for a while and probably missed some patch notes. Are death timers longer? I just feel like I stay dead for way longer than before. Even the other day, my team was ahead, but we had a bad teamfight around 30 mins and got aced and the other team managed to destroy mid inner turret, inhib turret, inhib, the 2 nexus turrets and win the game. Overall it just feels like an ace past 25 mins costs you the game, no matter how many towers you have left. So, how longer exactly are them?
