Historically rare. There have been 10 shutdowns in the history of the US government (there have been other funding gaps, but none of those had furloughed employees). 3 of those shutdowns in this decade. 4 in the 80s and 3 in the 90s. The shutdowns in the 80s were one day each. The 90s were 3, 5, and 21 days each.
