The company that hosts this blog has just informed me, that they plan to upgrade the database on the server 13 February. Hopefully that shouldn’t cause problems other than the approx forty-five minutes downtime. If you can’t get through to this site on Wednesday, please try again a little later. If the problem remains, then something has probably gone wrong, and I have started working on “Plan B”.

Update (February 14th):
It looks like the database upgrade went fine. 🙂
