Cancellations and Schedule Updates
Unfortunately, the W3C calendar system does not handle cancellations very gracefully. Cancellations cannot be reverted, and yet the event still shows up in the calendar mashup. It's also not possible to delete events through the UI, only by sending an email to the W3C system team.
Therefore, if a meeting is marked as "tentative" in the W3C Calendar and if "CANCELLED" is in the title, it actually means it is cancelled. This may be done occasionally to allow a cancellation to be reverted if necessary.
The start/end dates of recurrences can however be updated reversibly, which can also be used for revertible "cancellations". This has the advantage of removing the events from the calendar mash-up here. Several meetings (Architecture, Discovery, Security) have now been "suspended" this way, with their end dates changed to July 15, 2024. When they are reinstated they can be found under "Past Events" and the start/end dates modified.
Likewise to "delete" events just end their recurrences at some appropriate date.
Holidays and Upcoming Events
- no holidays and events
Cancellations
NOTE: Security, Discovery, and Architecture meetings are suspended until further notice.
Other cancellations:
TD teleconferences cancelled November 5th and 6th
Note: Please look in W3C Calendar for updated Zoom invites. If you see both a cancelled meeting and an "active" meeting, it means a meeting had to be "uncancelled" by creating a new entry, and the meeting WILL be held. There is unfortunately currently no way to delete cancelled meetings or revoke cancellations.
