During approach to ZZZ on ILS tower issued a terrain alert. Checking the HSI I noticed no glide slope indication. Added power and pitched up. Glide slope returned immediately from the top. Followed the glide slope to the runway and landed.
Twin Piper pilot reported ATC issued low altitude alert due to continued descent following loss of glideslope information.
