Two months ago we turned on support for rssCloud on WordPress.com. Today we’re announcing some improvements.
Initially rssCloud limited update pings to the IP address that made the notification request. To get around this a domain parameter was suggested, that included a challenge mechanism to verify the notification request. WordPress.com now supports the domain parameter ( and challenge ) for rssCloud notification requests. The WordPress.org rssCloud plugin supports it as well.
An issue that was specific to WordPress.com also came up. Under certain conditions it was possible to get a cached version of an RSS feed that didn’t have the most recent post in it, even after receiving a rssCloud ping that the feed had been updated. Now we make sure the feed cache is updated before sending out an update ping.
Enough of the technical bits, how about some stats! More than 135,000 blogs hosted on WordPress.com have at least one rssCloud notification registration. During the first week of October WordPress.com sent an average of 83,000 update pings per day. Today we average more than 105,000 update pings per day.
We’re just at the beginning of the trend towards push notifications, keep an eye out for more announcements in this area.
