OK, so which would you like first? The good news is that the database upgarde went well and web interactions are fast and scalable. Cool.
The bad news is that under load overnight it suffered teething problems and only the first few thousand mails went out. So we'll be retstarting shortly once we can keep the connection going for the time required.
UPDATE After researching this we've discovered the likely problem (it relates to how database connections are reused by the server software and FeedBlitz's highly parallel architecture). We've put in a series of changes to mitigate these issues. Today's smaller updates have gone out fine, so we'll see how well tonight's run (containing this post) goes.

I don't seem to have any story or click through analysis? What's going on?
My post from Saturday 6/17 went out, but yesterday's did not. I too am disappointed by the failure to post on the reasons for the service interuption.
As long as I know what's going on I can tolerate short-term problems with the upgrade. But this is all too reminiscent of my bloglet experience.
Just wanted to add a comment here. First of all, I do appreciate the hassles everyone had. I would have responded on line but the comment notification was going to a dead email address (oops) and I didn't pick these up. As you may imagine we did have a lot of calls and emails, and we tried to get to them as soon as we could while we were getting the system back up and running, including udating the posts. I had thought I'd got to everyone by the time some of these posts were written, so if I didn't get to you I unreservedly apologize. As I noted on the 20th, if there are posts you want to have sent out that we missed please let me know.
Phil
