I currently have several 10's of thousands of subscriptions active on pubsubhubbub.appspot.com, superfeedr, wordpress, and other hubs. Starting on Feb 6, I noticed that most of my subscriptions from pubsubhubbub.appspot.com stopped posting updates (other hubs continue just fine). Using the pubsubhubbub.appspot.com web ui, I noticed that many of the feeds I spot checked have an expiration time in the past (i.e. are expired). I see through recent messages on the group that the status of hub.lease_seconds is changing, and that it may not have been supported on the Google hub anyway. My endpoints currently see and correctly handle hub-initiated lease renewal requests.
What is the current suggested best-practice for renewal (on both 0.3 and 0.4 spec hubs)? Should I always initiate re-subscriptions?
Thanks,
