Upcoming maintenance May 17. – 20.

There have been some minor service hickups lately, so over the next weekend I’ll do some maintenance work, starting on Friday afternoon (ca. 15:00 UTC).

If all goes well the service should be fully restored by early Sunday, but I planned for the full extended holiday weekend until Monday evening, just in case.

Things to do:

* upgrade the OS from Debian 11 to 12
* re-import of the full osm planet database to fight data bloat
* rollout of latest MapOSMatic and Ocitysmap versions
* finally getting the Weblate translation service running again
* testing

There were some prior compatibility issues with Debian 12 when switched the server from Ubuntu to Debian last summer, these I’ve now fixed so running the latest stable release is now possible.
