Waleed, you may want to check http://superfeedr.com. We do polling if
we don't find any other way to get the feed updates in real time
( pubsubhubbub, rsscloud, sup...)
We send you the notifications thru pubsubhubbub, so if at any point
you want to move away from us, that's easy.

I have an app in production that pulls 250K feeds, and I'm hoping to
offload my feed pulling to PSHB and start to get updates faster. A few
questions for the experts here:
1. I remember hearing that Google's hub at pubsubhubbub.appspot.com
does polling every 3 hours for feeds that don't ping the hub. Is that
accurate?
2. If the above is correct, then I'm planning to start by simply
subscribing to all my 250K feeds on the Google hub. I'll get instant
updates for some feeds, and 3-hour delayed updates for others, which
is okay with me. Does anyone see a problem with this plan?
Falling back to polling isn't a required part of the PSHB spec, and
while the Google hub *can* do it, it's not great, so it's off in
production. Plus we don't want to confuse people as to what Hubbub
does. So no, the Google hub can't be your feed poller.
3. Is the Google Hub production ready? Can I expect, say, 99%
reliability or higher? As in, expect 99% or more of new updates to be
delivered to me?
There are no guarantees, but it's run on App Engine, which is pretty
reliable.
4. Does it handle non-English content?
Of course. It's all either treated as just bytes, or Unicode,
depending on the codepaths.
Thanks,
Waleed
