Yes, Registry Services has regular service windows for system maintenance. Up-to-date information is regularly shared on the Registrar website, registry.se, and through email notifications to our registrars.
Planned system maintenance for the year can be found on The Swedish Internet Foundation's website, https://internetstiftelsen.se/en/domains/tech-tools/maintenance-information/
On the specified dates, we will carry out maintenance work on our technical systems, which means that our systems may be unavailable. System maintenance starts at 21:00 CET and ends at 02:00 CET at the latest.
Note that this should not be confused with "releases", which we perform almost daily without downtime. Nevertheless, if a "release" requires downtime, we will inform you about it well in advance.
