Thanks for the confirmation. Indeed, my monitors seem to have returned
to 'all clear'.

Welp! That's a lot of IO.

Sharing from my own experience with a tiny publication point: I estimate
there are about 4,000 RPs deployed on the Internet. Assuming their
synchronisation attempts are evenly distributed across the hour, a
naieve calculation suggests every single second a new client will
attempt to connect.

Much appreciated!
