AI Summary: This GitHub issue describes a problem where event pages for unreleased events are directly accessible via their slug, even though they are not publicly linked. The proposed solution is to add a check to the event page handler to return a 404 status for any unreleased event. Although the event data is already public elsewhere, this change would prevent direct access to unreleased event pages.

AI Summary: Event start and end times, sourced from 'ilmomasiina', are being displayed in UTC instead of the local timezone when the site is running in an Azure environment. This indicates an issue with timezone conversion or display specific to the Azure deployment.
