Today there was a delay in crawling, so some digests will seem a little behind the times. I'm running multiple crawlers to catch up now, and have learnt a good lesson in managing the crawl cache! I'm investigating and testing new options for the feed cache right now, and will have something ready for the 'next level' soon. Thanks for your support.
It also seems that the server upgrade is now all ready to roll Friday morning/lunchtime (UK time), so those in the US should wake up to a better functioning FeedDigest tomorrow. :)
I'm still working on a migration for today but a few hours later than anticipated! Verrry busy :)
