• DBA_Dom (4/2/2010)[hrI am saying that we were somehow somewhere given the impression that the system default that a server starts with out of the box was a fill factor of 80%. Maybe my instructors were only use to earlier versions or something.

    The default fill factor ('out of the box') has been zero since at least SQL Server 6.5

    The most likely explanation here is that the sever-wide default had been changed to 80 using sp_configure at some point.
