    Roughly 2-3 times per year, so far.

    Thank you, @drwilco. As a quick follow up, are IP changes announced before they are implemented?

  • Rogier Mulhuijzen

    Yes. First the API endpoint is updated, then we post an update on status.fastly.com, and finally after a little grace period we start using the new IP space.

    The status page has an RSS feed, which also alerts you of maintenance and any network outages, so it's a good idea to put the feed somewhere you will see its updates. A lot of our customers add the feed to their ops channel on Slack, for instance.

    It has generally been multiple months, or even up to a year, in the past, but it's a good idea to try to act within a couple of weeks. So once a week like the script does should suffice indeed.
