even better is the view from the Paris bureau at
https://hpiers.obspm.fr/eop-pc/index.php
which at the moment is showing a Vondrak filtering
of the data with the predictable tidal terms removed.
Even better would be to remove the UT2 semi/annual variation.

caveat is that plot may change before you all look at it.

The rotation of the earth's crust started accelerating right when
the CCIR decided that we should start using leap seconds.
