Just a short note, that I am aware of the fact that this site's https certificate expired some time ago, that is August 7th, 2020. As all computer systems, even this one requires some maintenance work.
I plan to fix the problem in the near future, but right now there are other things in mind.
Thanks for reading. Kiitos kun luit.
Followup: Certiface now renewed.
Updated November 20, 2020: Changed title and added the followup note.
