@superfeedr I’m having problems connecting to push.superfeedr.com and pubsubhubbub.superfeedr.com — both worked briefly then continually return either “Connection Interrupted” error, or (weirdly) a brief HTML 500 Error page followed by a Firefox “Connection Interrupted” error. isup.me/push.superfeedr.com seems to confirm this isn’t an issue with my network — any idea what’s going on?
