It's been the longest shutdown ever. A short shutdown doesn't usually effect very much because departments have extra cash in the bank. This time it's going on long enough things are actually starting to shutdown.

No, historically that's not been true. You'd see slowdowns at the end of the fiscal year as contracts and other things change over or have to be renewed (so one office is busy making the contracts and others may be slowed down waiting for them). But a full on shutdown has been rare.

Most departments, however, do contingency planning so things like this should be available with minimal tailoring for the current situation.

It might seem that way, but since 1997 there have been only 3 shutdowns:

2013 under Obama over the Affordable Care Act

2018 under Trump over Immigration

2019 under Trump over the Border Wall (still ongoing)
