Information about our planned system maintenance for this year is posted here, https://internetstiftelsen.se/en/tech-tools/maintenance-information/
On these dates, we will perform maintenance work on our technical systems, which means our systems may be inaccessible. System maintenance starts at 21:00 CET and ends at 02:00 CET.
Note that this is not to be confused with "releases" that we carry out almost daily without any downtime. But if a "release" requires downtime, we will inform about it well in advance.
