Game pace sped up? What happened

Today, while playing (Feb 7 2015), I feel like the game is running at ultraspeed, as in everyone including me is running soooo fast. Like ghost speed and I was playing TD. Holding knife or sniper both feel much faster than usual, and because everyone is running faster, matches are more intense, explosions everywhere. Is that a modification the developers made to Crossfire? Or I'm just seeing things? Or is something not working right?
