Viewing the department's events through Google calendar does not always work. Google automatically fetches the events from the department's event feed but occasionally fails to display some events. Google has acknowledged the problem with automatically fetched events. Users of Google calendar can, for the time being, double check the event information at http://www.cs.helsinki.fi/en/news.

Google gathers user reports about the known problems possibly to estimate their prevalence and give a suitable priority to fixing them. If you encounter this problem you can report it at  http://support.google.com/calendar/?hl=en by clicking "Known issues" → "Google Calendar sync" →  "Some subscribed, imported, and synced events not displayed in web interface" → "Report this issue".
