Maintenance calendar

Subscribe to the DAIC calendar of maintenance windows and service changes.

  less than a minute  

DAIC publishes planned maintenance, downtime and service changes as an iCalendar feed:

https://doc.daic.tudelft.nl/calendar.ics

Subscribe to the feed rather than importing the file. A subscribed calendar updates when the feed changes; an imported calendar is a one-time copy that does not receive new or changed events.

Subscribe in Outlook

Outlook for Mac only offers Add Shared Calendar and Import ICS, neither of which subscribes to a feed. Add the subscription once in Outlook on the web; it is stored in your TU Delft account and then appears in Outlook for Mac, Outlook for Windows and the Outlook mobile app.

  1. Open outlook.office.com/calendar and sign in with your TU Delft account.
  2. In the left sidebar, select Add calendar.
  3. Select Subscribe from web.
  4. Paste https://doc.daic.tudelft.nl/calendar.ics, enter DAIC as the name, and select Import.

In classic Outlook for Windows, Home > Add Calendar > From Internet subscribes to the same URL.

Outlook refreshes subscribed calendars on its own schedule, typically every few hours. The calendar is read-only.

Other calendar applications

Apple Calendar (File > New Calendar Subscription), Google Calendar (Other calendars > From URL) and Thunderbird (New Calendar > On the Network) subscribe to the same URL.
