Explanation
No. A table tennis serve that touches the net does not automatically lose the point. If the service is otherwise correct, it is a let and is replayed without a point being scored.
The 2026 ITTF laws reproduced by Table Tennis England state this in rule 2.9.1.1. PongFit's practical guide gives the same explanation: a serve that clips the net and otherwise lands legally is served again.
The condition matters: touching the net does not rescue a serve that is otherwise incorrect. During a rally, a return may touch the net and still be valid if it reaches the opponent's court correctly; that contact alone does not require a replay.
Key takeaway
An otherwise correct serve that touches the net is replayed. During a rally, a valid return can touch the net and play continues.
