We see occasional requests from customers experiencing problems with Timetastic Calendar Feeds not updating external calendars.
Unfortunately resolution of this issue tends to be a waiting game:
An important aspect to understand about ical feeds:
It is your calendar application (Outlook, Google, Apple, etc etc) which periodically requests an update of the information from Timetastic i.e. Timetastic does not push the data to you calendar, it's your calendar that requests it from Timetastic.
Although you calendar will automatically request an update from the Timetastic feed, the timescales can be somewhat unclear and occasionally calendars seem to stop updating or have large delays - we've seen as much as 1-2 days.
I wish we could provide something more concrete on this subject, but it's the one area that seems to crop up occasionally and is very frustrating (for both you and us) yet there is little we can do.
- Some clients have reported success by deleting the feed from your calendar completely and reinstalling it, it seems that in some instances this is sufficient to kick start the updates again.
- We have seen instances where clients server firewalls block Outlook from updating the iCal feed from Timetastic. To fix this, they configured a firewall whitelist for Outlook for our IP - "184.108.40.206".
Otherwise we are genuinely sorry and like you, wish there was a better solution to this issue.
