We did the same thing at PubSub.com with updates that came in from FeedMesh
publishers and it worked very well. However, I would strongly suggest that
you be very generous with the amount time you wait before polling a site
that normally pushes data through PSHB. We should be able to rely on PSHB
hubs to normally do the right thing. Polling thousands or millions of feeds,
"just in case", is not a particularly good use of the network. At
PubSub.com, I think we waited 48 hours before doing a "just in case" poll.
Even that was probably too frequent.
Sorry, but I highly disagree. As I stated, PuSH is an augmentation to
polling, not a replacement. If updates are missed due to any of the possible
reasons (publisher bug, hub bug, subscriber bug), that data still needs to be
published. 48 hours may be the best thing for your servers, but it's not the
best thing for the customer.
I know for certain that if any of my projects were to go more than a
couple hours without publisher content being updated, I'd have everyone from
corporate CTOs to Joe Blogger beating down support's door. This already
happens with polling, regardless of where the problem lies. PuSH simply
increases the publisher's expectations and, if anything, they start getting
upset even earlier if updates fall behind because they now expect near-real
time publication.
