EBT and the forum will be unavailable early Thursday morning between 03:30 - 04:00 CET (approx) for rebooting to the newest CentOS kernel. The kernel that we're currently using may have issues with the upcoming leap second at the end of the year. I will also update the server's RAID adapter's firmware at the same time, as it would also require a reboot.
Relatedly, it looks like MariaDB still can't handle leap seconds properly so you won't be able to enter a note with a timestamp of xx:59:60. When I tried to set some entry's timestamp to the leap second moment manually, the timestamp ended up being 0000-00-00 00:00:00. This is unfortunate, but there's nothing I can do about this.
Edit: Downtime was approx 03:39 - 03:59 CET, or 20 minutes.
