Narrative:
On an ILS approach to cle runway 23L, with WX of 300/1 we had to go around due to the GS indicator went full deflection up, then full down, and then up and down 1 1/2 - 2 dots several times between 1400 ft and 1000 ft. Cle tower immediately told us that the critical area was protected. Second ILS approach was normal.
