Today, on the night from the first to the second of September, the Habrahabr server will be slightly updated, and therefore the site may be unavailable at times. In general, everything should happen “on the fly”, but if an empty page suddenly jumps out or something terrible - do not worry, this is very, very temporary. The update is exclusively “systemic” in nature, the software is updated, not the engine, so it has nothing to do with the new “features”, you can not even ask about them here.
In general, we warned ... :)
UPD. Like a minor upgrade completed successfully, without any special incidents. Good morning everyone and have a nice day.
